TFS: DIY Custom Exhaust from Scratch
Вставка
- Опубліковано 2 жов 2024
- Every car needs some kind of exhaust system. When you want something better than you can buy off the shelf, or something more unique, you'll need to know how to build it from scratch with nothing more than some mandrel bends. In this episode, Justin the Fabricator breaks down the fabrication of a complete exhaust from start to finish on a Maza FD RX-7.

👇👇ABOUT SOLAR FLUX AND BACK PURGING IN THIS VID BELOW 👇👇
ua-cam.com/video/AIRWMhoke9I/v-deo.html
The Fabrication Series can i go to your shop next time i go to vegas really fan of your job ??? great job sr
So, for exhaust fabrication (DP, MD, catback), its better (less expensive) to use solar flux for back purging, than back purged with argon? I am guessing its a matter of money?
Masacote motors Sure. Just send me a message ahead of time so I can be here.
knonfs Solar Flux is a less expensive alternative.
What about the back side of where you welded those hangers? Were you able to get any flux in the pipe behind them and if not with the tension and vibration is there any risk of cracking?
awesome work, taught me some things i didn’t realize and i can’t tell you how many times i’ve done an exhaust! love rx7s but mad respect when you asked please don’t slander my clients car. you’re the man!
Very Well Put!!!!!
Who can't at least admire the blood and sweat poured into this car. Nothing sounds better than a turbo rx7. Except maybe a cammed out classic big block, but those are everywhere
I wish I would have watched this before doing my own custom exhaust. I would have known a couple things to look out for ahead of time. Very helpful info and good lessons in here.
Lol i like the part where you were like "please don't say my client's car sounds like a fart. I know it sounds like a fart, but he likes farts" XD
😂😂😂😂
🤣🤣🤣 This comment is hilarious.
Ohhh man you can't beat the sound of a brapping rotary! And beautiful welds like always my dude!
It wasn't even brapping lol
@@lakessbm it was trying to 😂
Best tig welder in its class on the market still today. I love that I can change the EN and EP independently. Let’s you do stuff with less heat or extra heat than a normal inverter can do. Btw great video I need to do this for my ram learned a lot with solar flux and v band. Your videos are awesome man, thank you
Thanks for not allowing clipping in your audio. I’ve literally watched all of your channels videos over two weeks.(I just bought a tig))First welder).... it’s great to see you when you were much greener. 🇦🇺🤛🏼🤜🏼🍀😎
Love your work!
Very inspirational stuff.
Thanks. 👍🏻😊🇦🇺
Absolutely glorious craftsmanship, but there is no way I could listen to this all day driving.
You got some serious skills Justin. Great job!
Never seen such quality welding and preparation in my life!!!!! KUDOS
I love the solution for the possible haters! It you don't like the way it sounds bring me your car and I will make it sound the way you want..lol.. I would love exhaust done by you if I was a little closer
A very gracious entry to a lowered car. I am almost 45 now, but I still love the stance so all my cars are on bags so I can get in and out with a "little" more coordination and less cracking of my joints🤫
Very much the same way I build exhaust systems (yours come out better), except there is no way I could do it that quick AND film at the same time. Big props, you make it look easy brother.
I think it sounds great! I am a plumber and a tig welder. Usually working on big construction areas with big stainless and steelpipe welding. Great video, thank you very much.
I am going to weld my own exhaust for my Golf R and found this educational. Exuse my spelling, i am from Sweden. Keep up the good work!
That sound tho man its epic and so crisp well done.
I get so many tip from you about all sort keep up the great work 🤙
I love the exhaust and I am a big Rotary sound. You are an artist with that TIG.
Let’s admit NO ONE expected that exhaust sound 😂😂😂😂😂😂😂😂😂😂
Except anyone familiar with rotary engines. It is a typical rotary sound. Sounds even better (louder) with a hood exit.
A real craftsman makes the job look so simple. Holy crap man, you made that look like a kid could do it! Beautiful work!
Awesome work on that exhaust
Wow! That was the best diy video of the century! (I didn’t like how it sounds) but hey, what a beautiful job dude!
Thank you!
Nice job. Love the Brap of a rotary engine. I grew up around them and learned how to work on them.
Very impressive and that had to be the best sounding fd I've heard in a while . Very good job man. Beautiful car
0:50 I feel the struggle of being a big guy getting into small cars lmao.
i’m 6’7 man, i feel your pain
Great tutorial. Hate the sound but great tutorial and very nice job on the exhaust over all.
Nice work. I like the sound of my V8’s but for that engine it sound awesome. I have been dabbling with rig welding exhaust and find your videos very helpful. Now all I need is a lift and some good band saws. Saw your video on good saws as well. But working out of my house with attached garage I can’t justify or have room for cool tools like that. So I have been purchasing angles. And thanks for the hook up on that as well.
I think it sounds amazing
Nice work for sure, I’m more of a displacement guy so the sound isn’t for me, but it does sound formula, which matches the ride, so it’s a win…
Dam good vid mate and with no help you still managed to squeeze in so much info... Have watched it a few times so I have the master yoda skills to attack my exhaust tommorow... Thanks for making it enjoyable to watch, nice work and the Mazda sounds on point
Fantastic sound beautifully made
Thanks again Justin. Great video like usual. Can’t wait to do the exhaust on my Vette.
daym you keep on truckin! last vid i saw was bending some tubes for a roll cage! Still awesome and good advice 💪💪🤘
It sounds awesome, you do great work. Nothing but props buddy. 👍
It sounds like a fart!!! Btw, nice tutorial Justin, you made my late night
I'm so glad you said something about the sound... so I won't say anything as I come from a BIg Block family!- however, your fitment was good and this was a good video
wicked cool and wicked loud and very nice sounding
Great work, and that rx7 sounds amazing!
I've made a few exhausts in my time and I can back that this is all correct. Building exhausts takes a long longgg time, amplified by any restrictions the customer puts on you and the material the exhuast is made of.
And yes, alot of the exhaust making process is just a bunch of educated guesses where you hope if you are wrong, you just over shot so you can cut back.
Actually, no math is required to make an exhaust. You can do it all with a sharpie, band saw, a few peices of paper and a few clamps. Don't forget a welder and maybe a soft faced hammer.
Good job , nice video!
great job.nice fit,nice sound,great welds.
Very clean job and mad sound
Super helpful vid man, doing an exhaust on my own car now and this one was filled with great stuff…thanks for the upload..:)
Hello i am not a specialist in welding, this is beautifull car and great work, but when you weld v-band, try to have it connected to second side and tied up by bolt, this will prevent bending one side by heat.
🤣 That opening scene. 🤣 That me and every vehicle not based on a truck chassis. 😏
Excellent work!
Nice work. Oh the fireballs that’s thing is gonna spit under decel. 🤘🏼
rotary goodness. nice job!
Perfect car for daily driving 😎 and it s not that loud _ i like the way you work, very nice video
Awesome straight, love the rev sound, idle sound out of breathe though.
Great work!
All that work for it to sound like that lol. Good work man
Fantastic work mate! I want to learn to weld & build by own stainless V-band front pipe, so this video was great.
You gave lots of useful information & tips, plus I like how you get it as straight & tucked as possible... To me that is the sign of a very well designed exhaust for flow & power 😃👍
"Your Ad Here" sticker is hilarious
isnt that a Jon Lajoie thing?
Cars like this we naming "The box of a death" )) Because if you get stuck then you dead.
I never could get the hang of TIG. Gave up on TIG, but I do have a good MIG and do know how to use it...somewhat. That solar flux seems like a great product, no need to purge with nitrogen I guess?
You are a true master. Great job 👍
Yep I love it
Professional job well done, im very ocd with when it comes to doing my own fab or having someone do it 4 me. I never tried that solar flux I'm looking forward to trying it.
my guy, (
Mad skills man thank for the video very helpful
All the people saying it sounds terrible! It’s a Rottery engine that’s the sound they make. Awesome sound
Sounds amazing! Love it!
loving it
Mazda's greatest achievement in automotive history. how tall are you to barely fit into 1 ?
Can you make a video on how to weld the hanger rod onto the pipe? I find this way more complicated than pipe welding
Like you said, exhaust is a personal preference! This one is well made, which is what really matters. While I enjoy a well muffled rotary, because you get the full range all the way from a smooth buzz, to a furious scream, some wants all of the fury, all of the time. And that is perfectly fine! A rotary never sounds bad anyway! It looks great with the twin tips as well!
If I was 10 years younger, I'd totally dig the volume. I love the sound, but I'd like it more quiet or on demand if it was my ride. It's all up to the person driving it haha.
looks great! very nice job
Now, why was I here 4 years ago ? Deja vu all over again.
This is a great vid! It helps out a lot
great video thnks, great exhaust well done!
Great video
Que show adoro este canal tenho uma oficina de exaust systen aqui no Brasil e aprendo muito com vc
Nice job!! Sounds good to me. Keep up the great work!!!
That's amazing video man. Great job out there!
the tech and car is awesome. i know how loud these cars can get. in my opinion, Japanese tuners have the best sounding RX7s
Watching him squeeze into the bucket seat was was golden 😂
Great video as usual. I'm really looking forward to your HTP review. I've had one for a while and haven't had the time to tinker with it much. I'm in the process of moving, but I did disconnect my stove to borrow the breaker so I could try out the welder. Welding is way more important than eating!
I am going to school to be a welder and I'm currently building a new exhaust for my car. I straight piped it a year ago and this time I'm doing an actual exhaust entirely from scratch including a custom muffler. This video helped me a lot to be sure everything in this exhaust is fine tuned when it's all said and done. Thanks so much
Big Man gets in little car. I've been through that drill a few times. :P
How much do you charge for a custom exhaust?
Great work loving it!
Can you make a video on making an exhaust for a engine with two banks. All good on making down pipes on a single bank engine but how do I make identical down pipes other then just making two of them.
Great Vid man. Awesome tips too
Nice car and nice work.... great job Justin!!!
Nice work on both the exhaust and the filming. So it is possible to make these cars sound more throaty?? I sure wish people would drop the note to something other than CHAINSAW.
Your a God Justin
Is it an issue that solar flux wasn't used for the hangers.
Or did he pre-empt where they would be required and brush the solar flux beforehand.
Talk about a crampt space, thats why i dive a minivan 🤘😄👍 excellent video and Beautiful Car. P.S. ArtByAdrock recomend you and i wanted to check out your channel.
Beautiful work. Needs about 6 more mufflers. These bad boys are insanely loud even with the same exhaust that would be sensible db on a piston car.
180? 360? 0? what DOES IT ALL MEAN?!?!?!
that's a joke folks. functionally, they are all the same-- straight.
Well timed video for me Sensei. My exhaust parts are in the mail.
Quick questions:
1) What were the aluminum settings you used to get us newbies started in the tag team class with Bob? I forgot to take notes on that. Awsome class by the way!
2) I keep having an issue with the aluminum jumping up to the tungsten?? Hopefully I am doing something stupid and easy to fix.
Thanks
Email or message me on any of the social media pages. It's easier for me to respond than in these comments.
why not use a flex-pipe at the downpipe? won´t it leave a lot of unnecessary strain and vibrations at the header and/or downpipe, to make it without one?
The short answer is no because it's RWD. The long answer is most factory installed flex pipes are to reduce noise, vibration, and harshness (NVH) in vehicles. Most RWD cars and vehicles with uprated engine mounts equal less movement hence no need to worry about the engine bouncing around and taking your exhaust for the ride. The more movement your engine has the more movement and stress on your exhaust consequently.
Love the sound of an angry rotary, but I bet your neighbours just love you for firing that up late in the evening!
I think it sounds exactly like it's supposed to. Seems to be a track car, what with the lack of cat, so just let that sucker breathe. Nice work
Are you kidding? That sound was like sex for my ears!
High revving rotories, subaru boxer burbble, a big v-twin, and certain diesels are pretty much the best engine sounds out there.
Chris O I totally agree.
I'm with you man! My 05 WRX 2.0L with Headers and Turbo back 75mm pipes is music to my ears at any RPM.
His rattle is the sway bar support bracket is missing a bolt
how realistic do you think it is for me to do this with a harbor freight flux welder with no experience?
thats a big dude
Good lord, I miss my 7.
What is solar flux and why do you use it on the inside of the welds? Is it required if mig welding an exhaust? Cheers :)
What range should one expect to pay for this?
