LOOOOOL
Mines was stollen from me, quite frankly I kinda don’t want it back tbh
Actually quite a common problem... But nonetheless, sounds like you got a decat!
Me too! Mines was stolen last night & I don't wanna lower my 2005 Trailblazer just to keep some lazy thief from stealing my new Cat! I already run a Dynomax muffler & 93 octane so why not do a delete?🤷🏾♂️ When I was getting my new muffler put on ,they had guys taking the Cats off of new vehicles & hauling 'azz down the street 🤣 I was like daaaayum 🤣
I just take the clogged one off and drive a small pipe thru it and remove the inside no problem
took mine off and got some good cash for it,then I found out people be leaving them under there car!!! I know stupid, but my Sawzall paid for itself 200 times over
Bro same my car broke the shaft left in front of the house coming back tomorrow was so loud I checked under was cut of in da middle I like the sound it got but it’s just too loud even inside so I’m lil pissed
No cat. But i do have a resonators. But if car sits for a few month it will smoke for about a day. I store the car during the winter so everyspring i have to do minor maintenance. Its a 92 3000gt and no cat for 28 years. But i only put 22k miles on it in the past 18 years. But it runs great😂
That was very informative, so thanks for posting. Now we know!!! I subbed.
Thanks for the support
Awesome video! Very underrated!!
Thank you for the support 🙏🏻
Moral of the story is, "I prefer to keep my car Catless".
I have a Lotus Evora GT. Fabulous car with a great sound! I did the GRP 3rd decat and cold air intake. Now it's a more fabulous car with a better supercharger sound added to the orchestra. You may know this, but the Evora has a valve that keeps the sound low until you open it up by choice.
This is the Best Video Ever 👍
Excellent video
If we have to strip mine the earth for these precious metals are we really saving the planet?
nope, on top of the fact a single cargo ship produces more emissions in a year than every car in the U.S. put together does in several years. "cats help the environment" is a myth, the benefit is so tiny its like spitting on a forest fire and saying "im helping"
@@pepsilove6306exactly but not only that, these massive corporations that run certain factories to produce power and other things aren’t held up to the same scrutiny we regular people are. They can say putting these emissions restrictions on them would be too costly ,restrictive and unconventional but if I were to say that because the cat themselves cost me several thousand as well as the mechanic charging me another thousand I’d look bad and as a irresponsible low life. Talk about a double standard and how governments aren’t congruent with everyone
Great video!👏🤙👌
Thank you. Appreciate the support 🙏🏻👍🏻
6:20 A resonator installed just after the pipe bends from the front will eliminate drone or where the cat was.
Any old resonator?
02 sensor spacers are amazing if you have no cats and need to pass emisssion
I was looking for this comment, where can I get those?
Amazon or auto zone
Have you ever tried a Dynatech Torque muffler ? This is installed as close as possible right after your short headers, it provides more torque.
Some idiot stole my converter from my Honda fit last night. $850 for the repair. Chicago, IL. Great video. thanks.
Sorry man. This keeps happening across the globe. That really sucks. Unnecessary expense. Thanks for the support.
I love the reactions, got a 2006 f-150 with the 5.4, it’s a true dual muffler and cat delete
I've got an 01 2 valve 5.4. Cat delete stock muffler. I like how it sounds. Not even very loud
I seriously hope with your F-150 that you park on hills with the emergency brake on, because I know of a few cases especially with heavy loads, eg. A trailer that the parking pawl on the transmission fails and or the parking lever detent mechanism fails and the lever falls to reverse!
This is an issue that Ford refused to recall their vehicles for as far back as the early eighties!
Just a friendly warning that many Ford drivers are not aware of!
@@kychristell1779 oh shoot I’ve got the same engine and doing the same to my truck tonight!😂
@@kychristell1779 btw just curios what did you do with the 02 sensor?
@Sam's Back its still attached. I re used all the stock tubing just instead of the huge cat, it's a pipe.
Shoutout to you bro. The explanation is top notch
Thank you bro. Appreciate it
Great video 👍🏻👍🏻👍🏻
Spare a thought for those that follow you because they have to breath the stink coming from the exhaust. If I can pick a catless car so can the cops.
I've tried catless but soon put the cat back in because of the drone and stink, WRX. I've also fitted HF cats and they give great results, with no downside apart from the cost and the exhaust smells sweet.
Thanks!!👍
I love the smell of a car without a car my ba falcon is decated and I find myself standing behind it a fare bit
Do you need a tune after? Is it bad for the engine if you don't tune it?
I have a Isuzu kb250 dteq with 160k kms on it. Is it good for a turbo diesel and the longevity of the vehicle?
Will fuel economy increase from a decat ?
Also mine is a diesel turbo charged vehicle.. will it effect my turbo
awesome video mate, ive got a jeep jk and waiting for my longtube headers. Contemplating whether I should do a car delete myself, but im terrified about the smell aspect lol
Thanks man appreciate it... That's exciting bud. Look, if you did do the cat delete, it will definitely smell. Especially in the beginning. With time it settles. Or maybe you just get used to it 😂. From my experience it settles and you might smell fuel every now and then.
Did you ever do the cat delete? I’m looking into doing one for my 2007 Jeep Wrangler JKU?
@@thomasp5082 hey bro, i ended up replacing the 4 old cats with new ones. I tried without the cats and highflow but damn it was loud as hell and smelly. Imo having your cats will be much better and it dosent make the jeep sound like a honda. Its got a good low rumble and not too much drone
@@Hack8_ great thanks, just what I was looking for. I don’t want it to smell lol.
@@thomasp5082 you will need extension harness for the 4 o2 sensors btw.
great video
Thank you 👌🏻
Mine are out of my 07 f150 and I love the sound!!!!😁
I had to get a new downpipe on my car and it was about $650 because they HAD to put 2 cats on one pipe. About 2 years later I get the infamous P0420 code. I try a spacer on the O2 sensor and it works instantly! So FK buying more cats, i just hollowed out these new ones and the spacer still works AND it passed inspection. Yes, she runs better, accelerates quicker, is slightly louder, but she's got 220k miles and she's so happy to have that restriction removed
So to resolve the check engine light where can I take it to or can you make a video on the last part about dealing with the check engine light after the delete?
I just watched a video where the guy used a couple of spark plug defoulers on the down flow O2 sensor to rid of the check engine light.
Just curious if you have ever done a before and after dyna test to
see if you actually got more power with the CAT delete. I have done
this with a couple cars and there was a little power gain at red line on one and
the other actually lost power. In both cases, low and midrange power was slightly lower.
It is many times a thing of 'It has to be faster because I spent all this time and money
on the mod." A seat of the pants thing not based on actual tests like on
a dynamometer. Now, if the converter is plugged, of course things
will get better. But, if the converter is in good shape, the improvement
may not be there with a cat delete. A lot also depends on the engine management system
and how it reads the O2 and air flow sensors.
in general a cat delete can gain you 10-15 hp on stock engines, there are tons of b&a on youtube that show this. its louder more emissive. bigger cams/ high flow intake / boring the engine will all make the de cat much more worth it.
My car is tuned with full bolt ons. All the high flow cat did was cause a O2 code and a nasty smell in my cabin with the windows down. I have a 2.0t and noticed no difference between stock and aftermarket. Honestly was a waste of money but lesson learned. Stock cat, tuned, full bolt ons and car still pulls good and now doesn’t smell like shit everytime I drive
My cat was stolen, and it took me 2 YEARS to notice! There was always a check engine light and my mech was advising that I need to change the O2 sensor which obviously didn't work on the long term. Second opinion discovered that my cat was missing ;D. So I did a modification on the cat space and added 4 layers of perforated sheets to mimic the cat.
This video is very helpful, and I totally agree the engine is happier, smoother; I experienced more power, acceleration; but these two mean there's less fuel economy. Yet to find out exactly how much more fuel I am spending
That's crazy man but glad you resolved the issue. Thanks for the support. Agreed fuel economy would be worse but engine happier and smoother power delivery
@@swiftysportsa Fuel economy actually might be better, at least not worse. Its not about fuel consumption, its about how much you use this new discovered power to impact the fuel economy ;)
How did you not notice the converter being gone for 2 years?? My god you must be deaf.
@@j.t.cooper2963 Yes, I am actually deaf, and it's not illegal to be deaf. Do you feel better about yourself now?
@@MatthiasKavuttihCampHeritage Well that certainly explains why you couldn't hear the difference in the exhaust sound with a missing converter. I never said it was illegal to be deaf so actually I have no feeling about it at all.
I’ve been dealing with so many exhaust issues with my subaru lately. I find it so stupid they would create a vehicle to burn up so much oil because they can’t make the piston rings the right size, then maybe put it on a one owner under 100,000 mile warranty if u bother the shit out of the dealership to fix it, not necessarily garnered to fit it either. But if you keep adding in oil, it only later ruins the catalytic converters and eventually the engine itself
Where i live their is no inspection and we say what is a cat?
I'm a newbie, so I did the cat delete and put a free flow muffler. I love the sound and a little performance gain, but it's too loud, is there anyway to reduce the sound a little bit? Maybe replace the muffler? I heard one of those hks legal mufflers make the sound bassier and reduce the loudness quite a bit.
Any luck?
08:16 no, because downstream o2 sensor role is to check if cat is ok and no spacer can make needed signal that will prevent eng ch light, only by deleting second o2 by software
From my experiences the spacer only has delayed the CEL atleast in the cars ive had.
Great video! I have a question tho, i recently upgraded my intake and did a tuning (engine remapping). is it better to do a cat delete?
Thanks man! My opinion is that your engine has now been mapped with better airflow going in but the same exhaust pressure coming out the back. It may be possible that your tune may show better results if you now go and cat delete as well. BUT this isn't guaranteed. I would speak with the tuning shop, if they think your current remap will benefit further from a cat delete.
@@swiftysportsa hey, i just spoke with my tuner and said that the tune is ready for a full system exhaust. So no need for re tuning. I'll do it next weekend. Thanks for the response bud.
@@IvanDoesMTB That's great man, gonna sound awesome and take advantage of your remap even more now! Enjoy
If you need cats and have to have Safety inspection only no problem emissions just gut your cat and put back on install spark plug defoulers to keep the check engine light off and good to go
this guys got the right idea
I had two on each side of my truck ,and with almost 200k miles on ,and one blown engine at 150k ,which is when I obtained the truck, which also had codes for insufficient cats ,but was not affecting performance at that point yet, just a little sluggish, but very smooth running though, however at 198k started running really bad ,and I could hear rattling coming from the cats ,also pinging from the engine ,and the exhaust smell was volatile if you happened to start the engine with the door open ,and let some of the fumes in ,I reckon all the material inside the cats was acting adversely at this point ,so I had no choice but to remove them ,or replace them to continue driving to work ,no I only have a lean code ,but over all ,a happier engine , if your area requires smog ,you shouldn't do this ,but I also believe that our Country could ,and should produce it's own cleaner burning fuel ,which is most definitely possible, and would make Gas burning cars ,and engines much safer for the environment! Thanks for your video ,awesome !!
My engine also pings and rattles at times I thought the heads were dirty could it just be the cats ?!??!
@@enriquesanchez7747 definetly could be the cats ,check your engine codes ,it should tell you ,if you don't have your own code reader beware though ,you might get ten different answers ,and suggestions ,a common thing for Auto parts places is tell you it could be just o2 sensor ,so you go ahead ,and buy those first , not putting down parts house"s, they're just reading codes ,only trust your own code reader ,lol !
@@edwardippoliti626 hi sir, i'm in the same situation. Do you think cleaning cats will resolve that? i'm from europe, and some professionnals can clean them (with special machine and products), the process cost around 200 bucks per cat. Only issue, i'm not sure if my cats are obstrued or really off.
@@SRTvespucci707 Well it all depends ,if they're clogged, then clean them out ,if they bolt up ,if not you ,1 straight pipe them ,2 buy new one's or universal cat ,they're out there for alot less expensive than brand new stock one's, also keep in mind your local smog laws ,because it might not pass smog if they require smog where you live ,the straight pipe is gonna be a little louder ,so keep your muffler, and you may have to drill out two spark plug foulers and reinsert your 02 sensors in them, for the behind the cats 02's ,also you'll notice alot less back pressure ,just make sure you have your own code reader ( or a friend's) and stay on top ,of your codes ,gas mileage should stay about the same ,considering you keep the same muffler,3 buy new ones if you can afford ,good luck!!
So, my cats actually plugged up preventing me from exceeding even 25 mph DOWNHILL. I've had the idea of taking the system out, shelling out the cats, and reinstalling the whole system with the muffler, would this bring the system closer to normal with back pressure and all?
you wont get the back pressure back. So if your model of turbo [assuming you even got a turbo] requires any back pressure to operate properly. I recommend replacing said Cat. But if you dont have to worry about that. I recommend outright removing the cat and replacing it with exhaust pipe same size as rest of your exhaust, because you can get a vortex effect that effects your cars ability to push exhaust out the pipe due to a gutted cat. Only reason you would wanna risk a gutted cat on ya car, is if you live somewhere with cops who got nothing better to do. Such as the ones who go "your car is too loud" and put an inspection mirror under ya car to see if you got cats and a muffler.
What about decats on AT car
Will a jeep wrangler 3.8 run efficiently without all 4 cats?
Enjoyed the vid brother!. I was wondering if you remove the cats off a vehicle. Do you have to get a tune or can you just drive the car like you never removed cats?
Thanks for the support man! You don't need to get a tune. You can drive as you normally would. The car would show even better results though if you decide to do a tune after along with your decat
Ok thanks for the quick response!
Can a basic performance muffler increase the car sound? Without removing CAT etc.
Definitely. My car came with a performance muffler from the previous owner and it sounded much better than stock. Gave the car a grunt still keeping the cat.
@@swiftysportsa thanks bro keep the videos coming, enjoying them. Thanks
@@Get_Mind_Fuel thanks man will do. 👍🏻
How can I increase the sound of my diesel jeep without installing a muffler?
Will straight piping it work?
Straight piping will work but will be very loud... I suggest go in sections. Most people remove their mufflers first. Remove one restrictor and see if you're happy. If not, remove another.
Diesels need more tail pressure. May not want to so that.
Good day - I have a 1.2 TSI really like the idea of cat delete and tune stage 1 (But some people say not to do the cat delete) Not good for the car. Just want to know your personal opinion on it for a daily car / Road trip car. Should I do downpipe + TUNE or Just TUNE.
Honestly based off of my personal experience, I did my cat delete over two years ago and haven't had any issues. Everything is mechanically sound. I have had only pros from my decat. The only con is the smell of fuel. You will get more out of your tune with a decat than without. But ofcourse you can tune without doing the decat. Up to you.
@@swiftysportsa Thank you. Really appreciate the response.
Does anyone know how to find the spacer/Fokker for the o2 sensor?
I watched another video ,where he showed how he used two spark foulers drilled out to accept the sensors, available at most parts stores".
ebay
What is this fooler exactly? Will a tune turn thr check engine light off?
A fooler is a spacer. It simply lengthens the 02 sensor so that it is not directly in the stream anymore. A "tune" can also work but this is not a performance tune. This is a change of fuel to air ratio purely to clear the error. This is a less common approach as apposed to the fooler.
If you're modding a car and tuning it will that get rid of a lot the smell? Because excuse me and limited knowledge of cars I'm above average but still a lot idk so bear with me with this question if it sounds dumb, but does a catless car stink with a factory tune dude to the car probably running richer because the tune is set to a certain amount of fuel or whatever with the cat on then when you take the cat off its running more fuel than the car needs so therefore it stinks more if that makes sense?
The car will smell regardless of the tune. Whether it's a factory tune or aftermarket tune, the exhaust is now releasing smells as the cat is no longer there to tame those chemicals. I don't believe the car is running richer however it is a good question as I did mention more air flow, more fuel, bigger bang... Something to research
@SwiftySportSA well looked up that a richer running run makes a bad smell too. I'm not saying Elimate the smell completely I'm saying will it minimize to to where it's not as noticeable cause I see people who do turbo builds never run a catalytic converter hardly ever so I wonder if the smell is really that bad due to the fact they don't do it. Maybe I'm missing something maybe the smells not as bad with the turbo on there? Idk. I haven't seen a aftermarket turbo build yet on a car so idk what the smell is like
@@swiftysportsa my f150 after a delete was stinky and it was indeed running rich, but its got over 300k on the motor and the cats was plugged so at this point, since I hate said truck im just gonna let it run rich and run it into the ground. It was running super lean and had zero power due to the plugged cats/ manifold issues i had, so i just deleted the cats and the o2 sensors [which is why im running rich] but i pull a trailer/mower set up.....no power was no good. Sooooo gonna let it rich itself to death and just finance that S10 i been wanting once it dies.
Mine had an injector fail which put raw fuel through the cat, so it’s toast
Would adding a muffler help with the noise?
Do you mean to help reduce the drone after decat?
Depending on the car, you might not notice much difference in the noise. I did a decat on my car and kept the stock muffler and resonator. As a result, the exhaust is just slightly louder than stock, and it's not annoying at all.
Yes, I got a car in which I did this and the check engine light never even came on. It's a newer model car made in Japan.
i only heard Performance gain and Loud Sound
only problem with stock cat is that it can be melted if floored too much
Thank you for telling me I didn't know that
Rev range???
Decat doesn’t improve power until your engine is well over 600hp on a single exhaust cat. Even less difference running dual exhaust. The reason is hot gases flow a lot better than cooler denser gases. The cats are red hot inside and increase exhaust flow. So as long as your cat isn't melted from raw fuel hitting it, than there is no reason not to run a cat. This has been dyno proven lots of times. In fact sometimes a car will lose a few hp without the cat, because the exhaust gases are cooling too soon.
even on older cars from 90s and 80s?
@@fortheloveofnoise9298 Physics and catalytic converters don't care how old the car is.
Well I didn't get to choose to do a cat delete, thats for sure.
Does poison Chinese come thru the vents ????
Torrey Pines, absolutely !!!!!!!!! but some people like the smell.
Will it mess up your car if you go catless without a tune or doing the spacer thing?
removing cats sounds cool but it decreases performance It makes the car run like shit after awhile
its wont for most performance cars other cars maybe
@@youngchard1292. . . contrary to research
Does it hurt gas alot?
If you drive economically you will actually gain MPG and save on fuel marginally. BUT when you floor it you will hurt your consumption more now as there is more air flow and as a result more fuel being burnt.
What about the high flow cat?
High flow cats are a great option. I believe it would cost more as you would need to purchase the specialized part. Everything I mentioned would be the same except less effect - eg. Less sound or different sound, less smell as it would contain some of it, may pass legal issues as apposed to a decat. Should still receive potential power increases and better throttle response as it is still a more free flowing system than stock
I bought a high flow cat and it smelled like shit 💩 unless you’re doing big gains a or yours is clogged no reason to delete it
My exhaust smells like sweet sweet corn! 😉 😉
Most people doing a cat delete don't give a flying F what other people think 😉
Yup
did you soft the car after cat delete?
or just plain removed the cat and thats it?
Software on its way soon... Will make a video on it
I have to say great video but you are wrong about the drone sound and not being able to get rid of it. Look up 1/4 wave resonator or j pipe. Work 💯
Thank you for the support and appreciate the feedback. Yes you are right this is also an option. It is an extra expense over and above the decat but yes I should have included this. 👍🏻
I'm in Florida. Nothing is illegal here, except for voting multiple times, and voting for the dead. As far as the stink, I think you're used to Armai's 😊. Cheers.
Florida #1 👍😃
cats are not too restrictive: on 300c 5.7 , stock was faster than with long tube headers and no cats
thats gotta be 100% bs or it wasnt tuned😂
@@imposing4141 long tube headers were bad
@@makantahi3731 Ahhhh unfortunate
@@imposing4141 and with log ex manifold, no cats, free flow mufflers 6.1 cam and tune, could not hit stock speed. now i am making long tube headers and re piping (OD from 63mm to 70mm) rest of exhaust, i hope i could hit 275km/h
I drive the 300 3.5 with pop bang tune onnit with cats in thinking of taking itnoff
LTH should be done at this time 😂
A big con is i4 accords and altimas running catless... Sounds god awful
Does it shorten the lifespan of the turbo?
It can cause the turbo to overboost so most people would do software with a decat to diagnose this and turn the overboost into a healthy mod.
@@swiftysportsa thanks
Does it effect the gas mileage?
Yes it should improve your mileage as there is less restriction if driving economically. Your car will not have to work as hard to produce the same outcome as before.
@@swiftysportsa I have a 06 jeep commander limited which has two catalytic converters but one of em is clogged. It would cost a lot to fix it so I’m just trying to figure out if I want to do a cat delete.
@@Lordfarquad518 if both cats are down the same pipe then I would remove it. It's cheap, changes the sound and will improve MPG slightly.
@@swiftysportsa would you still recommend doin it if they are after the split in the pipe? It’s raining right now but after I’ll check to see where they are located
@@Lordfarquad518 it's tricky man as I would imagine the air flow and back pressure being uneven then if keeping one and removing another. I'm no mechanic but I would imagine that's not an ideal set up.
High flow cats are an option
I’ve been debating this but the high flow cats dont seem to add much more of a dynamic sound
What is on your eyes that keeps appearing when you look to my right??
Does it effect mileage?
Yes it will effect mileage. You will see an improvement if driving economically as there is less restriction and engine doesn't have to work as hard, BUT if driving hard, then mileage will worsen as there is more airflow, more fuel more bang.
I'm gonna do a secondary cat delete only & install a high flow 3 inch pipe
Should sound very nice
Yes it turned out sounding really good, I actually wound up do a primary catted downpipe as well paired with the high flow secondary A pipe & a full cat-back sport exhaust & it's perfect
One dude worked at Midas had double thick wall pipe entire exhaust
on his dually
No wonder there are so many noisy trucks and cars nowadays, with all the stolen and self removal of catalytic converters! And we certainly aren't doing a good job here in Calgary
of enforcing the noise law!
Correct. You should see the amount of anti cat theft products that have been invented over the years to prevent this. However most of these products don't stop the thief, but simply delay the process.
None of the western provinces enforce cats on personal vehicles so might as well take them off preemptively and sell them yourself.
6. Pro: the air smells so sexy 👍😋
Because Race Car 💪🏻🔥
Ads on California tv way back said come to the races....the sound of burning rubber! the smell of exhaust fumes!
My catless Ford V10 with a glass pack sounds absurd. I need to tone it down a bit. My cat got stolen got to get a new one ha. Colorado laws suck though and the exhaust shops have to charge for California compliant overpriced trash, so because the law is unachievable for me, it goes catless. Sorry everyone I'd love to spend $35 to fix this myself but I cant get a regular car shipped here.
I took mine off and my car is so much faster
Does a cat delete increase RPM?
I don't think a cat delete increases RPM necessarily as you are covering the same Rev range your car allows BUT it definitely allows the car to work smoother through the Rev range. The engine doesn't have to work as hard anymore through the Rev range, so power delivery will feel better.
@@swiftysportsa well noted.
Thank you
Most people get rid of them
Just found out it's illegal to take out your cat...when I asked my muffler guy to do it
It can definitely be illegal depending on where you're from
yea most guys wont do it, you usually gotta do some driving around and find one of those little hole in the wall shops that dont even have a proper sign, who mostly deal in cash only transactions. Or if you know any tree shade mechanics they will usually do it and just tell you "you were never here if the EPA asks."
Welll Our provincial Government Rescinded Emissions testings.. Entirely . As it proved Pointless.
Beyond that when Bupinders' Gravel truck Stops putting out Twin Columns of Solid Soot at each gear change.... I will start feeling guilty .
Cat gutting changed the sound a Little bit.. but not v much at all, as Turbos do A Very good job of chopping up ex sounds .
Many ECU programs can be modded to delete the 2 nd (downstream) O2 sensor.
Front one doesn't care as it measure Before the catalytic.
decat for flames >>>
Yeahhhh
dont care. removed cat my car sounds like a dog now
Or someone stole your CC and you can't afford a new one.
I'm pretty shore it's illegal and there is large fines lol isn't this a illegal mod where I'm from if a mechanic notices it you cant leave until it's replaced or they are liable for a very large fine
So why are people stealing the CAT if it is not that important
They sell them for cash
Cats have a precious metal inside the cone. Palladium and / or platinum . Don't leave your cats at the muffler shop, especially if you just paid them. Some scrap yards would pay top dollars for cats. 💰 🤑
He looks and sound like Drew McIntyre wwe
Not one minute of dallas info.
This would be my worry: things have a way of building on each other...so you delete the cat, then your car is stuck in snow or something and gas come into your car, and the decat deletes you! From the dead! You are dead, when you would have been alive if you fixed it right/weren't cheap. Sounds about right. Or, the car drives poorly or the car starts to drive in a way that is harmful to expensive parts, and bam..this alleged savings ends up costing way more than it would have if you just did it right. Also sounds about right. Maybe it messes up the 02 sensor and causes your engine to run lean or something which messes up something else which causes a head gasket leak or you to blow a piston. I don't know. Head gaskets are caused by an overheating issue, but I don't know. I kind of don't have time to find out either! That being said, I'm going to straight pipe it. Haha Maybe I can find someone out front of Autozone to do it.
Everybody sucks on This Canadian comedy channel on sirius, but every once in a while on a blue moon, someone is funny. Such is this operation if it works.
If you have an exhaust leak somewhere in the system, you could die in this scenario you describe, with or without a cat. The cat doesn't take away the carbon monoxide that your engine produces. You should probably leave the cat in if you have a regular normally aspirated vehicle. Its when you have a lot of flow of exhaust (High HP) that the cat delete helps.
Different animal once ya let her breath!!
……skip to minute 8:06……
I have experience with cats car is more power more silent more compatible more mileage. Without cats car 🥵🥵🤮🤮🤮
The main pro is better fuel mileage! Why do you refuse to say this? I did have a 1979 cheverlet suburban. I ran headers and dual exhaust and was getting 18mpg highway. I moved to California and was forced to smog it. Mileage dropped to 8mpg. Please explain this.....
don't fall for the climate alarmism
Let's all decat! 😅👍🏻
You mean scientists
Exactly. Climate Change is BS. That said, my cat was stolen and I’m not replacing it only to have it stolen again. So decat it is!! 😅
Come steal mine off my ram
