Prius drivers usually don't even get to choose if they want to delete their cats, it just magically happens for them
That’s true and they also have a house full of cats so if they missed one they’d probably never notice.
Like effspot
@@njshift lmao
can relate
😂
As many other people have said, hiring Zach was one of the best decisions Donut has made.
Yeah, it's nice to just get information without all the dumb shit James does. I don't need someone crying over little shit in car videos.
Every single video of his has this exact comment LOL
@@TheoneandonlyJobis shut
@@TheoneandonlyJobis yes but james makes the up to speeds interesting with the little jokes here and there
Agrees
Late to the video, but as a technician, kudos to Zach for not only knowing his shit well, but for explaining it like a high school shop teacher. I say that because while we all love cars, not everyone knows the mechanical side of it all, and Zach does it in a way anyone can understand. Good job Zach! 👏
Yup, I am not a car person at all, and its nice to be able to still follow him along (mostly) with listening to him.
most of his knowledge is just a lot of research and experience. I could even say it is mostly scripted but I think he does know what he's doing.
@@therapgame1091 I think it was mentioned that Zach was actually a mechanic, which definitely helps. As a mechanic/tech myself he's been bang on with everything he says, so I definitely would believe it. There's definitely a big difference between a mechanic who can do the work, and one who can explain it in a way that all can understand. Definitely helps when you're talking to customers, especially customers who don't know how their vehicles work. I'd hire Zach in a heartbeat for just that reason
@@dhag72 I’m pretty sure that he’s mentioned that he used to work for ECS Tuning, though I could be wrong
@@thenerfherder9586 yeah he did. He did product research and development with ecs. And also a legitimate auto mechanic with a formal education in it. He knows his stuff
I’m 17 , and haven’t had a dad to teach me the basics like this, so I really appreciate you teaching even the little things. Not expecting us to know anything helps so much! Great Video👍🏼
Keep your head up, bro. You'll never regret learning how to work on cars. My grandpa always said, "If I hook you on tools now, you'll never need to be addicted to anything else." He was right.
Well we’re your E-dads so ask away if you have questions 😎
Not all dads know about cars
Your Dad is a bitch. You are awesome!
Never give up learning,knowledge 💪 💯.
Plenty of dudes/gals up in here to help you out.
Don't worry man I started when I was 15 learning mechanic with 4 of my friends. We all bought 5.0 mustang and would be blowing engines left and right. We started to rebuild our engine until we learned. I am now 31 and I have never taken a car to a mechanic for anything. And I do crazy stuff to our cars. I even learn how to paint cars. And yes all of the fluids in my car are like brand new before I replaced them. My brother's get mad at me for switching out the oil when it looks like I just barely put it in.
"Is a cat delete worth it?"
The law requires that I answer "no".
The law is the law and we can't change it
@@KitKitChanIsaac pretty easy to change actually. It's been changing since the first laws were made
69th like...nice 😎👌
I understood that reference. 😉
@@KitKitChanIsaac maybe where you come from. Federal laws in America can be changed and do regularly. Also they are usually shit and only for someone to make money within the government. It’s my car I have every right to replace my catalytic converter. I’ll cut it out as many times as I want to. Most states don’t even enforce it because they know it’s bs and people should be allowed to fix their cars. In California; good luck!
My welding instructor told me to never stand in front of the regulator handle when opening a pressure vessel. Because he was a trade welder for 20 years and he had seen one catastrophically fail blowing the t handle into the wall. He taught every student that came through his course really consise safety rules. Mr Elton you were a master RIP.
I wanna know what a t handle is so I can make sure to not do the same thing
@@stinkymans5002 it's the thing you turn on the regulator to change the pressure
@The Weapon Collection combination lol
@The Weapon Collection theyve all seen some shit i swear
Im currently in welding and fab class in my college. One time I seen a kid try to punch a hole in a piece of hardened steel. It fractured and one of the pieces wedged itself in the cinderblock wall. The kid was find but he almost fucking killed himself
I like how Zach teaches. He knows how to get information across, including some pretty niche stuff without sounding superior. It's a legitimate skill that not a lot of people have such fluency with. But Zach is just a super charismatic dude, so it's not surprising that he teaches so well.

Even just going from regular to hi flow cats, was by far the best bolt on mod I did power wise. The only mod where I legitimately felt a noticeable gain, and that was just swapping to hi flow cats.
What year and model?
Wait wait wait. You mean to tell me that you did a test, something didn't go as planned, and rather than just pushing the video out with skewed results like almost every other youtube channel I can think of, you actually put the effort into giving more accurate results? See? This is why I'm still subscribed to you guys. You don't just spam as many videos as you can, letting the youtube algorithm boss you around.
True, without the boost correction with the cat this would've been an inconclusive/unfinished video. When they mimicked the boost it really showed how little a difference the cat delete really made. I wouldn't do it for a measly 5hp increase.
Karen. It's just 5hp. It would be worth it with a full exhaust change because the full power gain can be significant. The combo of better intake and cat-back exhaust will give largely noticeable performance gains because the engine with respirate better.
@2D well they did switch back and forth relatively easy. Its not impossible to see you deleting the cat on race day and slapping it back on afterwards. 5 has isn't much until you're pit against a car that has more or less the same hp as yours.
@2D exactly my point. Sometimes you have to come to a compromise. If you track your car daily. Keep your straight pipe on and don't daily drive it. If you track it once every now and again, and your grease your knucks like you wash your hands, deleting your cat on track day shouldn't be a huge deal.
delete the cat i will dele the whole exhaust system
EPA: Cracks down on companies for deleting emissions equipment even on racecars.
Donut: Here's a video of us deleting a cat.
I didnt know racecars on racetracts had to comply to emmisions on private property
Read between the lines "test pipe". Think of how easily they were able to swap that pipe back and forth for different results. The cat could be called the real test pipe because thats one you will need in for the emissions test 😄
@@ghostwarhammer007 if I don't need a license / license plate on private property I def dont need to comply with emissions
fun fact: in canada we just yeeted all the emissions testing equipment into the scrapyard in 2018
i can order a black smoke belching ural truck, which i intend on doing, and there is no worrying about emmissions anymore :v
@@ghostwarhammer007 farm tractors have to these days.
I'm still relatively new to Donut and enjoying their videos greatly. I echo what others say, who have likely followed Donut for longer than I have - Zach is great at presenting and explains things so well. Great vidya!
Zach is by far my favourite Donut host. He just seems so at home with all things internal combustion.
In my country if you park your car in the wrong neighborhood Crackheads will do a free Cat Delete you just have to install the straight pipe
😄😄😄
so the US?
In the UK, they are currently targeting MX5s just for the cats, they are worth around £500.
In the uk if you park youre car anywhere you get a cat delete even on youre driveway
basically yeah I'm British too people just drive ride looking for s target unless you have a garage or secure drive way but nobody people have garages in this country since are houses are tiny whilst American houses average double the size and they usually have a garage or actual drive way
Most people in this country have to park on the street infront of their house but it's not your property or private but a public road and If a football match is going on and you live near a stadium well good luck If you haven't already parked your car
I cannot believe just how much Zack knows about everything
Always seriously impressive watching him work
He did know to put coolant on that blade while it was cutting.
He has a whole crew that writes for him....
@@zachorvik8361 that may be true but it’s still just him getting the work done
He knows the importance of doing the research before hand. He also took the time to invest and learn a core set of skills.
If I remember correctly, he did auto shop in school at a local college or something so he knows a lot of the actual mechanics behind why/how things work, but as I can tell you from experience, many of these things are things you actually just pick up along the way the more you work on cars. Zach just has the added benefit of an actual formal education and the backing of a solid car enthusiast set of friends that can all supplement his skills/knowledge. I’ll tell you right now, the biggest help/advantage you can get when getting into workin on your own cars is to surround yourself with friends that also work on their own cars. Everyone specializes in something and everyone learns form the others. It’s great.
This video is an absolute life saver! I've been looking for a place over here to set me up with a decat but so far no luck. Thanks to this video I can make my own. I've watched loads of donut media videos but none with this dude really informative stuff, so thanks!
It is worth it for older cars that need ZDDP added to the oil. It is said it will probably clog up catalytic converters. But old flat tappet engines really do need the zinc.
When he said “we got a welder” he was both excited and sure he was gonna get judged on his welds 😂😂
@@LachlanD1213 what lack of safety

Zach Jobe is one of the most charismatic hosts Donut has ever had, an absolutely fantastic addition to the team!
He honestly is the only reason I stayed subbed to donut media
Fr man
I like Zach, but I miss Bart from science garage :(
BART
How much did he pay u to write this?
Zach is the mechanic we all think we are but in reality we can only dream of being like that.
You guys are life saver been watching some of your turbo videos for the miata and leanered alot been trying to find a turbo for my 2018 civic it's a 2.0 6speed. It's been really hard to find the right one since I didn't know to much.
257hp in a Miata must feel like a rocket ship lol
Or a rocket bunny
Tyler Ray is making over 500
@@thefinalroman Taylor Ray.
I've driven a 270hp Miata, and yeah, can confirm that its pretty impressive
That amount is perfect. Still grippy and not too much but a hell a lot of fun. 500bhp is silly, where can you actually put that down. The Miata is about going down fast country lanes, not highway
I have a feeling that Zach knows the most about cars, at least physically, than anyone else at Donut.
I dont think that was ever in question he has a lot more past experience than the others
He was part of/or head of the r&d department at an aftermarket parts company before working at donut.
@F*СК MЕ - СНЕCK МY РR0FILЕ go away
He used to work for ECS tuning check their UA-cam
Or really good at delivering a mutually collaborated script... just sayin...
Also dumbing it down to anyone can understand and explain the basics in a very understandable way is very impressive, I only say this is because I had a stroke a couple years ago and I don't understand directions very well but this I can understand. Kudos!
Wow I really appreciate your talk throughs on the welding bit. I've found myself with a "weld bug" and have been actively working on learning the basics before ever actually getting a welding gun in my hands. Thanks!
The fact y’all went for the extra data is why you’re such a clutch channel. You checking yourselves and never have an agenda (other than a good time and education)!
Truly one of the best parts about it, so much more knowledgeable commenters would have brought it up
I mean, yeah, but this was a terrible choice of car for this test. The exhaust restriction on such a small engine is really negligible. it matters for more for larger or more powerful engines, where a cat delete is definitely worth it for more power, and that’s not even talking about the safety of reducing egts and back pressure. The cats on new cars are very restrictive to meet tightening emissions regulations (and ridiculously expensive), at the oem I work for we are having trouble even meeting last year’s power and torque ratings on the same engines.
@@jamesd2863 well said.
"Is a cat delete worth it?"

Please go sign the RPM act. (Make sure you read the act before you sign it. It is important to keep an open mind and understand what you are signing.)
@@deepwater4532 YES
I still have my cat but I removed it from my exhaust so it wouldn't get stolen.
@@deepwater4532 murica haha such a police state and 3rd world country
@@deepwater4532 You should tell people to read it first and understand the argument.
One tip about the band saw... If you keep your guide wheels as close to the material as you can, you reduce the blades penchance to wander while in the cut and should produce straighter cuts. Abviously as you mentioned, the cheaper the saw the worse the cut quality, but this should help get it as good as it can be!
i have watched money pit many times as i love zachs hosting and just easy understanding, this video in that short bit of weilding i learnt more than 3 months at college, out teacher didnt explain as well as zach did.
Came here to see if cat delete is worth it, came out with a degree in welding, math bachelor, now i know the best type of tools for this job and why the catalics are worth so damn much, amazing lmfao
I was actually annoyed by it 🤣
I was like is this a welding lesson 😑
Yet you didn’t learn how to spell “catalytic” correctly. Smh
LOLLL
@@bigwheel9132 English lesson is in the next video
@@colinkeaney559 And the correct way to spell “catalytic” is plastered all over this video. Sorry for calling dumb, dumb.
addition to the welding tutorial:
wear gloves. the light generated is like a more concentrated version of sunlight. it can burn you.
have proper ventilation on coated metals. especially galvanized.
other wise a great beginner tutorial. you can absolutely do what zack did with a $200 flux core 110v mig welder from harbor freight jsut by watching this video.
Harbor Freight products are a danger to humans
@@Lofi.z34 i'm not endorsing the crappy tool imports. lol. you certainly get what you pay for.
but i'd hate for any one to feel like they couldn't do this with their own hands just because they don't have a fancy miller touch screen gas fed welder.
@@Lofi.z34 I used a the harbor freight titanium Mig welder for the last two years before the gun died on me and I upgraded to a Miller. Don’t let internet hype get to you, harbor freight welders aren’t that bad at all. I started my welding buisness with mine. Well worth the $400
@@ChrisSadowski I got the Vulcan omnipro 220. Love it, honestly I use a lot of stuff from harbor freight, and I like alot of it. It's cheap, sure it's Chinese imported, but it works and that's all I care about.

Zach is literally the best thing to ever happen to donut. Knowledgeable and entertaining. Literally built for this
He reminds me of guy I used to work with it’s awesome when people truly love sharing and have a positive attitude.
Zach is that cool big brother who everybody wishes they had cuz they explain things to you instead of yelling at you cuz you don’t know it😂
Zach was my big brother's name. That being said, this Zach is probably cooler than my brother was...
Well said
I think my kids are older than he is. My older brother doesn't know much about cars, the one after me is not too far behind where I am. Zach can explain things to noobs quite well. I like him.
And Bart took that personally. (Lol just jokes Bart took me to this channel basically)
@@frankielight2696 same
“It’s a cheap bandsaw” A.k.a. it’s from Harbor freight
Exactly what I thought lol. Nothing wrong with harbor freight if it’s a tool you won’t use all the time
So true.
You can get away with a handheld bandsaw... With aftermarket stand even cheaper than that hf one...
The blade is really most important anyway
Harbor Freight: yeah we got a lot of crap tools, but most of it is satisfactory for your needs. Also, let's be honest, you're too cheap to buy the good stuff, and there's nothing wrong with that.
@F*СК MЕ - СНЕCK МY РR0FILЕ you have never felt the touch of a woman.
As someone who works for a high end welding company I would like to make one tiny correction, you don't necessarily need co2 to weld. You can lay down some pretty nice beads with just argon. However Co2 mixes are used in certain situations such as welding carbon steel or doing a carbon build up. Nitrogen can also be used for specific purposes as well. Love the Vid Zack.
Theres more than one kind of welding you know.
Personally I work with whatever I can get my hands on. Learning to adapt along the way
Great video guys, as always! You all do great work explaining things and keeping the audience, us plebs, entertained!
"I should probably put this cable over my shoulder"
- proceeds to weld with the cable not over his shoulder.
LOL
Wrapping yourself with the cable is something you should never do because of strong magnetic field it produces. So that was a bad advice anyway...
Welding is one of those tasks that seems really intimidating until you actually start to learn to do it. For builders it opens up a whole new world once you take the time to figure it out. Your welds dont even have to be pretty, just strong.
You speak the truth. I practiced for a few months with my first MIG welder and it really let's you graduate from bolting things together to legit building things yourself once you get the hang of it. Opens all kinds of doors as far as custom work.
A lot of off-roader people I talk to say that starting by fabricating bumpers and rock sliders and such that don't need to be pretty, just functional, is a great place to start. And your first few will look ugly and you will be self motivated to get better at it lol
Yes that’s very much true. I’m a welding student, currently working on my highschool endorsement. And yeah, when you look at welding, it seems harder than it actually is. The terms, and machines you use is quite different than your average mechanic’s work shop. When you make a weld, it’s true that you really need to make sure the weld is strong. I’ve met plenty of welders that thought the welds had to look good too, and then took a grinder to said weld. They completely ruined a perfectly strong weld, because of a simple misunderstanding. The main thing to worry about is making it strong, but it’s ok can make it look good with a strong weld too. But it takes quite a bit more skill, than just grazing over learning welding basics.
Grinder and paint make me the welder I ain’t jk don’t take my advice but true to an extent if your welding for real on the big time weld inspection will hit you if your weld isn’t right ... worm tracks penetration there is more to it the farther you get involved with it but mig is good for any diy junk these days tig and stick are where the moneys at
TBH Welds almost never look pretty, that is why a grinder and paint is a welder's best friend as it will get rid of the ugly and make them welds look niiiiice. I learned Mig and Tig, and I prefer Tig as it makes much less of a mess, but Mig is so much faster and easier lol.
Your excellent instruction on the welder has inspired me to buy one, so I can make my own downpipe. Thank you!
You do an amazing show with the explanations,knowledge,and humor keep up the great work
Scumbags in my city are deleting people's catalytic converters whether they want it or not. It's a big problem right now.
Hey sounds like a win win, let me just place my sports car on the street and hope they steel my cat... of fuck.... my wheels are gone!

Thought my 4runner just had a really rich cold start and that's why it was so loud. Until I touched the throttle lmao
I’m glad the disclaimer was there, otherwise the EPA was bouta mulch this channel.
The law doesn't grant people the right to remove emissions control equipment "for track days". People aren't allowed to remove/modify emissions control equipment on street cars. Period. This is literally an example of why the EPA has opted to crack down on this stuff... let the registration lapse, pull the plate off, transport it on a trailer then it's fair game.
@@BTrain-is8ch yep, and honestly it's getting annoying, ever since the EPA has started raiding people UA-camrs have been saying "Cat delete" far more often.
When in reality they need to just stfu, everyone and their mom who knows anything about cars knows getting rid of the cat increases power, especially in turbo cars.
@@BTrain-is8ch In my state, you are not allowed to have an Unregistered Vechile, Period. Doesnt matter if its Offroad/Track only, has to be registered and have plates, even if it doesnt run.
The EPA also didnt "Crack Down" they have been raiding and shit since the 80s, the news is making it out like this is some new thing, its not. The EPA doesnt want you to have a Race Car, they dont want the NRHA, they dont want Nascar, they want everyone in Teslas and Prius's. The fact we still have them still, is a testament of those fighting the never ending battle.
They also dont take into account that the Electricity needed to power everyone with electric cars, would cause more issues than the Gas cars do now. They have unfeasible Ideas, and logic based on Fear and not data. That is unless, everyone went to Solar/Wind power to power all the Cars, because that just worked so well for Texas.
@@GOTTHEFUZZ Again they didnt just start Raiding people, they been Raiding people since the 80s. Its just that time of the year, and thanks to Covid they got less to do in office and more time to raid people.
Plus they have Biden riling them up, pushing them to enforce more, to make up for the 4yrs that trump made them chill out. Thats why they are trying for the RPM laws, not because they didnt want to before, it was because they never had a perfect storm, of a Pres, House and Senate, Electric cars, to actually pull it off till now.
Our Moron Govt, basically just banned Vaping, even with the Facts showing its a Harm Reduction, and every other country embracing it. We got morons in power, thats simply all it is.
@@cyberlocc I know nothing has changed. I know the EPA does this periodically. I've watched a few rounds of it and seen the RPM act come up each time. The EPA is in fact cracking down on it right now because they are actively going after brands/companies that sell/install/etc parts marked "for off road/closed course use only" that end up on street vehicles. I'm aware that there's no new law and the stuff they are dealing with has been illegal for decades.
Anyway, the EPA doesn't care about legitimate race vehicles because they are so rare as to be irrelevant.
P.S. Natural gas powered plants made up around half of the generation outage in Texas.

He’s really good at welding, a lot of correct patience, and beautiful 45 degree slant angles to connect the smaller piece to the larger with a lot more base around it.
This is why I'm here. Not a car guy (live in Manhattan, don't even own one)... I found Donut based on the Tool Party episode about rust removal, stuck around because Zach, Jeremiah, and Justin were super entertaining in that episode. Literally the first few days I found y'all, the Tool Party eps were the ones I watched first because I just found your approach interesting.
Now I'm working my way through Money Pit and Zach's hands down one of my favorite UA-cam presenters at this point, and now I just accidentally got a welding tutorial because why the hell not.

Paper is weak cardboard
Cardboard is just shop grade paper
When I was in A&P (Airframe and Powerplant) school doing my sheetmetal training, I wrote out my calculations on the metal I was working on with a sharpie. If it works, it works.
I've always ran an external wastegate with no cat, so maybe that's why I'm able to control boost easily without creep, except when I had my smaller turbo trying to push it to it's limit, usually getting a couple pounds of creep
as someone who has been certified in welding through school and works for a welding company i can say u worded and explained everything perfectly when it comes to helping someone to understand the basics of welding
Then you agree that a tig weld would have been preferable over a mig in this situation?
No MIG is fine. Why bother with the additional headache with TIG. It's a test pipe, it's not hold pressure, not holding any weight, nor does it need to pass any AWS or any other wps protocol/inspection. No one is going to see it or really give a shit what it looks like in the end.
@@fyreleya3005 because tig is exceedingly stronger, less porous, better depth of penetration etc.
@@fyreleya3005 I'm not saying MIG isn't fine I'm saying TIG is always preferable when you're looking for a solid non porous seam with deep penetration.

I blew my cats out in my 350z. Replaced them with aftermarket 'race' cats and the sound was horrible.
@@ThatGuyFromThatOneApp In my book it would be the other way around, if u wanna free the engine souund u shouldnt hurt the enviroment by deleting the cat lol.
I just wanna say thank you for putting that yellow bar the length of the ad so i know how much to skip

Very cool video... Welding is my next adventure and this was the best explanation of it I've seen yet.
I'd like to see a high-flow cat tested ad well. It'd be cool to see stock, high-flow and catless with a comparison of power and also emissions. Measure ALL the data!! :D
Man what car guy actually cares about emissions levels though?
@@benb5308 Well for starters any that wants a road legal car that will pass a legally mandated vehicle inspection where a missing catalytic converter is an instant fail. I know this is a strange concept for Americans.
@@BigUriel yeah pretty much any Americans other than those in Canada. Mandatory vehicle inspections are bullshit and I'd refuse to live anywhere that has them. If your lawmakers are dumb enough to think vehicles are a large factor in co2 pollution than car inspections are probably the least of your worries
For me it's because I still want a little back pressure so I don't strain the header mainly because I've been there. Also I don't like to have more volume than tone. Just want that tad bit of extra power when I swap the exhaust system out
We do not need a cat here in Florida,been catless for years in my 96 Jeep XJ!
God man. Zach is like the dad I see teaching their kids about cars. I had my dad but he wasn't a car guy. He fixes what he knows but that's it. So it's cool having such a great person like him teaching me
Dont give up! I'm the only gear head I'm my family and no one ever taught me anything, but I know alot of stuff now so dont give up and keep learning 😄
What Zach tells me to do: buy thousands of dollars worth of tools and weld together a pipe
What I do: $40 angle grinder, some pipe, and a few exhaust clamps
Your using pipe? I used old soup cans!
@@devinbender8428 i used a couple paper towel rolls

Just do a muffler delete too and call it a day.
Epoxy and paint make me the welder I ain't
Yeah I think alot of people would like this video but on a NA vehicle to see if it makes a difference with our normal cars, maybe even do a muffler delete vs mufflers and cat vs no cats on NA
Got a 96 mustang gt. Flomaster mufflers and off road h pipe. Those 6 cats weighed 200 pounds. I don’t know about power but sounds awesome and better mpg
More Zach focused videos teaching us please; this is insanely educational
" she is flat, she is cheap, and she is for a 2 1/2 inch pipe"... I thought you knew my girlfriend for a second
I’m finished😭😭😭😭😭
We all do....
Gold
You have a 2.5 inch pipe? Sorry, dude.
lmfao
It would be really interesting to see the stock cat compared to a high-flow aftermarket one. And then compare that to the test pipe after you fix the boost creep issue.
I believe StreetFX from Australia did a car vs no cat vs hi-flow on their 800~ HP Supra. Cat delete added fuck all power. Not worth a 10k fine down under. Smells like shit as well.
@Shndon430 Hurtado high flow cats are designed to have a negligible impact on flow compared to a straight pipe. Much higher flow than normal cats, which themselves typically flow better than mufflers.
@@Phymatic There is not a Cat in existence that can handle 800HP engine, so that doesnt add up.
The highest HP cat you can get is 700 for a kooks green. After that, you will melt them constantly, they have to be removed pushing past that point. Lots of people have even fried kooks at 700hp.
@2D Link?
Also a Link to that being proven. Because that would be the first I have ever heard of that.
Unless you talking about those Vibrant GESI, because I can already tell you, those don't even handle as much as Kook greens, that's marketing not Reality.
Thats why the Vernon's have like 6 cats lol.
@@cyberlocc I'd have to find the video as it's been a few years since I've watched it. Their Supra was not running a cat to begin with but they added one for the video to see the real world difference. IIRC they lost like 6 WHP from adding it. I kind of recall them being high 700 WHP maybe just over 800.
Very interesting and professionally measured test. I have certainly assumed that no cat is better than an old cat (or maybe even new cat) . I let a new cat work while it can, don't need another one. I suspect that the benefits of the "test tube" are maximized at top rpm.
Very helpful! Thank you!

Honda Fanboys: *heavy breathing*
God all the stock civics with diffusers, splitters, spoilers/wings are just foaming at the mouth at you, you be spitting mad fire XD
Its practically a f1 car now
I lsx swapped my civic and for some reason I still said "wow"
@Ryan Couchman if you meant civic then Ohhhhhhhhhh yes I did a lsx engine in my civic
$$$ to HP ratio is pretty good, that scrap steel probably cost $10. A CAI that performs that well will be over $100!
Reminds me of when a guy came into my work and wanted to put a motorcycle battery into his Civic, for weight issues. I told him if he's that worried about saving a couple pounds try a diet.
Like the time a guy came to a maxwell spot and asked if they had anything to drink with low no sugar cause he has diabetes I murmured under my breath yeah they got water.
@Philosopher Dan absolute sigma male badass
Civics (the sub 00 models) work with riding lawnmower batteries... Had one in mine for a summer, hahaha. (Not for weigjt though)
Just do a solid state
I once got a warning in an online forum when suggested something like that in general 😂
I use a chop saw with cutting disc wheel, for cutting exhaust tubings, works well.
Yep... got4 bandsaws in my fab shop and that little model (sold in UK badged as Clarke) is my go to for thin walled materials 👌 Cost me 10× less than my next size up. 🤙
Zack - "Is a cat delete worth it?"
Cats- "What the *meow* bro? >:C"
6:29 "Most welders have just two knobs... with random numbers on them." I'm worried for the miata...
Gotta keep those that don’t know interested.
I mean, he's not wrong for most *basic* welders.
Great video! Used to have a mk2.5 MX5 2004 from new had it a couple of years but loved that car! Had the bullet proof 1.6l which was more reliable than the 1.8l version which is why I chose that from factory and not much different out the factory cos the lightness of the car! Went BMWs after cutting my teeth on that for 2 and a half years but miss that car ever since I SERIOUSLY want another one but the rust issues on them especially in England are a nightmare they're getting scrapped left right and centre over here but if you're prepared to do £1000/1500usd of welding on them they can be saved in a lot of cases, but it's a big job and then you gotta get the respray etc so you're throwing money at em for sure unless you get one that's been garaged all its life and never seen water or salt and they're like rocking horse shite and command £6-15k. Btw you can't decat them legally in Britain cos the emissions test on the annual MOT they have to pass, so great video especially for over here!
Cheers from London England 👍😎🏴
Super late to this video, but any chance you could tell me what angle measuring device you’re using? I’ve found similar but nothing as simple and easy to understand as yours! Great video, and like the other peoples comments I love how you explain everything in detail and break it down in a way that is understandable and people can learn from! This is what makes this channel so great!
I really like how Zach explains things, this has been a good series.
The cat delete making big power gains comes from the early pellet type cats that were much, much more restrictive than the modern honeycomb type cats. Try this experiment with an old Dodge turbo from the '80s and you will understand why the cat delete trend started.
the cats on new camaros and corvettes are almost NEVER ever deleted in any performance application because they are designed so well there is simply no reason to delete them.
@@mathewhoffer4541 They get forcefully deleted if you park it in any urban area. BYO straight pipe, though, only the disassembly and removal is free.
@@GTAIVisbest lol 😂
@everyday tenor or tune it 🤷♂️
@everyday tenor It being street legal depends on where you live. If there's no emissions testing which is far more common than people seem to realize then it's worth it if you have the coin.
im amazed at how well the information here is simplified
Huge gains just from a cat delete.
Zach kinda feels like the older brother I wish I had so far he taught me more than my dad about cars
awhahaha same
“Is a cat delete worth it?”
The EPA: 👀
Can you say "Diesel Brothers" ?
This isn't the smartest thing rn
@@adamwonder2207 ?
@@trevorreid9142 the epa revised the clean air act and stuff like this (which was already illegal) is now super illegal.
@@trevorreid9142 they go after people that make videos about removing factory exhaust and putting aftermarket so jts not smart to do this at this point of time
I did this to a Crown Victoria. Was a decommissioned highway patrol car. The sound was improved a bit. But there was little to no noticable improvement. Removing the dampener from the driveshaft however, made a huge improvement on acceleration
I'm more of a dog person, but deleting a cat seems cruel.
You can tell this guy works his ass off for these videos. Kudos.
true, but we could have seen a lot less of the fab process. at most, this video should have 5 min long and was disappointed to see this done on a turbo car, i want to see the gains on an naturally aspirated car.
@@zerocool6257 You could always make your own video
@@sethallison5682 not exactly, he’s gonna have to get a wielder, a car to build a pipe for, all the parts for the pipe, and something to cut the pipe.
6:45 even the cameraman nodded their head🤣🤣🤣
I use to program robots in automotive assembly lines. Leading the weld results in deeper penetration then pushing it, so you can use less heat to get same penetration.
Nice video and good subject. I subscribed.
Question: What MIG/TIG welder do you have?
Thanks,
Paul
“Yo I need to put the hose on my shoulder to not get caught on anything”
*immediately welds with hose on lap*
It hurts when I wee
It's called a lead not a hose 🤣🤣🤣
Bro wtf
also moved pipe & flange to edge of table...
I tig weld with the lead on my lap
Taking notes on a scrap of cardboard with a sharpie. Perfect.
Pretty standard in most shops tbh, cause paper gets black faster
Making use of the old CAD. Cardboard Aided Design.
Most relatable part of the video lol
A job fully finished is a job well done. Respect gained, good job dude.
when it comes to mig welding if you are right handed you should push from right to left and the opposite for left if you dont it can cause a lack of fusion and penetration
