    1971 Jeep CJ5, 225 V-6, I am trying to manufacture a new exhaust pipe using flowmaster mufflers. My jeep has headers and it is currently pieced together with straight pipe and flex pipe. The exhaust muffler on the passenger side is mounted at an angle between the drive shaft and the frame in front of the rear axle. When I hit a bump it bumps against the drive shaft. Their is not much room for the muffler. The muffler on the drivers side has alot more room so the muffler can be welded in parralel with the body and should not be a problem. I want to use the flowmaster muffler because of the noise reduction. Does anyone have a picture of their exhaust system that they could post. Welding everything together is not a problem its just finding the right locations for everything. Thanks in advance for all the help. Lee

    I used some turbo tubes on my cj3b :v6:and love them. I think I went with about 14" ones or so. They sound really nice, but not loud and much easier to fit up in. ran 2" duels.

    Try a search I recall a couple of different options that have been well pictured. iirc check Mike Boyinks page I think he had some good exhaust system photo's.

    are glass packs gonna sound like total crap under my rig? I have the 225 with chrome headers that come out the outside of the frame rails and want as low profile mufflers as possible. How close do you think I can safely put them up to the underside of the floorboards (whole tub is Hercullinered inside) and if you guys have a suggestion on another relatively cheap (55 bucks or less a piece) muffler that is low profile (4" thick MAX, 3" would be better), let me know. Thanks guys.

    FWIW, after changing my dual exhaust setup back to original, engine performance was much better and quieter.

    At idle it sounds like a cammed V8. At speed it sounds like the original Busch cars (V6), pretty good but there's no mistaking it for a V8. Niether is overly loud. Pete's never had duals, so I can't really give a comparison. I changed to a DUI ignition at the same time as the exhaust and I suspect most of the performance gains came from the ignition. Pete does run and sound great so the set up is sound. What I like best is its completely tucked up between the frame rails w/ just the tip of the tail pipe showing.:v6:

    i just put the same set up as you have, minus the extreme, i put on an older flowmaster i had in my garage. i don't really like the rapping sound it makes when down shifting and changing gears. does yours make this sound? what did you pay to have yours done? it does sound great at idle though.

    Yeah it raps off a little but not too bad (nothing like a glasspack). The extreme is basically a super 44 w/ a thick case (one of their smallest mufflers) so my tone and/or volume may be different than yours. A guy in town here (fellow jeeper) did the pipe for $150 and I supplied the muffler.:v6:

    I have duals with both mufflers on the driver side. They are angled. The tailpipes exit on each side. The passenger side exhaust is longer than the driver side. The passenger side crosses over in the front runs back to the muffler and then back over the diff and out the back corner. The driver side is pretty much a straight shot.
