Building a Bedside Exit Exhaust on a Jeep Comanche: It's DONE and SOUNDS AWESOME!

I've always liked how the Jeep Comanche looks, and finally I've gotten a chance to work on an MJ Jeep! This one is a custom rock crawler sitting on Dana 60's and one off link suspension and coilovers up front, and while the suspension and chassis work was already done, this rig badly needed an upgrade in the exhaust department. My job was to install a header on the 4.0 Jeep inline six with a V band connection instead of the ball and socket style, then fabricate and TIG weld a mandrel bent exhaust system from 2 1/4" stainless steel. Two additional requests by the customer were a bedside exit with the exhaust going up and over the frame rail, and a teardrop cut tip on the end, so that's exactly what we did. The muffler is a Magnaflow oval 2.25" center inlet offset outlet oval body muffler, and sounds pretty dang good on this 4.0 inline six!

FINALLY got the comanche done! Maybe now I'll have some time to work on my own projects

[@gregquante8864]

Don’t be so sure. If the right people see the quality of the work you do I think you’ll have plenty of people wanting you to work on their trucks

[@michaela1655]

I heard somebody say "If you aren't showing it, you aren't doing it". LT is showing it and doing it....and the results are so fine!

[@redlyne624]

Would you ever consider doing a couple videos on welding? Mig and tig. Everything from machine selection, to setup, accessories, your welding table, and the process to achieve the best welds. The videos you produce are inspiring.

[@erichildreth7562]

Man another top notch quality exhaust build from LT!! You have some unreal skills my friend!! Can't wait to see some more and now I want to learn how to do this kind of welding!! Thanks for sharing this with us!! :)

[@bdugle1]

A week’s worth of time! If I’m doing my own, I’d be happy. If I had to pay shop rate, maybe not so much. Beautiful work, though! BTW LT, I’ve had to do a lot of grinding on my own project, C-notches, various other mods. My wife insists, rightly, that I wear an industrial dust mask doing this grinder stuff. I also do woodwork, have an acquaintance who has done it his whole life-he’s now living with major lung issues. PPE is there to keep you healthy!

[@redsmerf]

See, this was informative. I've got a '78 F-100 stepside that I'm going to end up doing an exhaust on. I was thinking either side exit under the steps with a square/rectangular end-piece, or keeping it hidden/tucked up under the rear step bumper with a downward ejection. Now I just need to decided on which muffler....

Great Job LT

Great job LT! I like your comment on the amount of time it took. Sometimes its easy to think you just whip these things up in an afternoon since it's just a 16 minute video.

Looks good. I want to do something similar on my 4x4 turbo Colorado

[@mikealexander4166]

That would sound awesome with 2 more cylinders and revs higher than 4K on the ripems. Great job on the exhaust. I don’t think people really understand the time involved in customs. I’ve built a few boat and make all my own hardware. You can spend a day on 1 bracket between the lathe and the mill. Maybe I’ll hit the lotto and be able to afford a CNC machine one day. Can’t wait to see what’s next.

[@stelter99]

Nice work man, glad to see you on your own outside of power nation. I know getting that completed muffler and tip in was a pain in the ass, would have liked to see how you got that section in again after it was all welded up

[@LawrenceTolman]

went in pretty easily actually, there's plenty of room under the jeep to swing it up in there

[@zachboyd231]

Dude, you got me over here doing diff eq, calc, and trig trying to figure out a way to delete my exhaust there on my XJ. I believe the reason you want to avoid terminating the exhaust under the bed is because it creates a pocket of heat at low speed that affects the gas tank and whatnot. Sound too I guess but either way everyone else is gonna hear that thing from six blocks away.

[@teaguegearhart9851]

One down and another great one to come. When are we taking the saw to the suburban?? ;). Can’t wait.

Trade school or community College that has a welding program.

[@charlesmecum5009]

I wrk from my garage too and was curious of what u charge per hr for those of us not certain what we shld be charging

[@richardcoleman9645]

Wondering why you didn't close off the pipe ends and gass the inside of the pipe for a better weld? You used too i think.

[@Fosgen]

No shield gas from inside?

[@sogood4u489]

[@Ballsmcgee1011]

Hey LT, I notice you don't back purge when welding stainless. Are you using a special filler rod or something so it isn't necessary to purge?

[@LawrenceTolman]

no, I'm using just standard 308 filler and for ideal results I should back purge, but for most exhaust systems, I skip the step. However, if I am building anything like a turbo manifold or a crossover pipe that goes before a turbo, I always back purge

@@LawrenceTolman Thanks, but I was just looking for the vise (I already have a table), and it doesn't appear to be available from them.

Hey LT, the exhaust came out pretty bitchin'! Now if you can talk the Comanche owner into letting you do a Cummins swap for him' that'd be awesome, rigjht?

What about the O2 sensors and the catalytic converter?? It's going to run like an ass!!

[@sogood4u489]

It has the upstream in the header that's all you need the sensor after the converter is just there to make sure the converter is doing its job has no effect on how the engine runs, just gives you an annoying check engine light.

[@LawrenceTolman]

Yeah, it does have an o2 sensor in it, right after the header, in the factory location.

[@casperscustoms1578]

@@sogood4u489 This era of 4.0L only has 1 O2 sensor in the header. There was no second Post-Cat sensor.
