dancome433 Posted July 21, 2009 Posted July 21, 2009 how do you guys have your aftermarket exhaust setup? I'm tryin to get ideas for my mj, i would love to have it come out the side but if i bottom out then ill crush it, i saw a pic of one mj that they cut a hole through the frame and the pipe went through there, but i don't think the frame would be very strong after that, I'm thinkin of having it dumped unless any of you guys ahve any cool ideas
glundblad Posted July 21, 2009 Posted July 21, 2009 You are willing to cut a hole in your frame to run your exaust? :eek:
dancome433 Posted July 21, 2009 Author Posted July 21, 2009 You are willing to cut a hole in your frame to run your exaust? :eek: noo, i saw a pic of somebody who did it(I'm trying to find it but i can't) and i gave thought about doing that, but i don't think I'm going to
dancome433 Posted July 21, 2009 Author Posted July 21, 2009 I found the exhaust through frame pic, here's the link of the truck http://jp.automotive.com/25956/154-0710 ... index.html
89eliminator Posted July 21, 2009 Posted July 21, 2009 i just chopped my tailpipe right before the last 90* bend so it points straight to the back. never had any issues with hitting rocks plus it was a free modification.

JeepcoMJ Posted July 22, 2009 Posted July 22, 2009 borla header/downpipe/muffler. stock everything else, chopped straight off in the rear. I'll be modifying mine to be closer to the bottom of the bed though. my brother kept it with stock, but in the rear he made it come up through the bedside and out of the passenger side of the bed. he intends to have it through high water and wanted to eliminate back pressure though.
dakineJ Posted July 22, 2009 Posted July 22, 2009 I think that is CW's truck w/through frame exhaust. I think I'm going to eliminate the last 90* as well,mabye even dump it in front of the axle.
bgred2 Posted July 22, 2009 Posted July 22, 2009 I found the exhaust through frame pic, here's the link of the truck http://jp.automotive.com/25956/154-0710 ... index.html If I did that it would rattle so bad I would have to install a 100 watt amp for the radio. Look nice though.........
Automan2164 Posted July 22, 2009 Posted July 22, 2009 For every 90* of angle in the exhaust, I was taught that that is the equivalent of adding another 7 FEET of pipe in relation to exhaust back pressure and turbulence. Food for thought. Rob L.

Look nice though......... Just 100 watts? I am putting in 1200 watts soon. As Jeremy Clarkson says Power....
Pete M Posted July 24, 2009 Posted July 24, 2009 You can sorta see mine below. Just a straight shot to the rear exhaust hanger and a slight down tip on it.
landlubber Posted July 24, 2009 Posted July 24, 2009 mine looks just like pete's. and on the new one, it ends at the cat.
dakineJ Posted July 24, 2009 Posted July 24, 2009 For you guys that have ended the exhaust after the muffler, has there been any problem with exhaust fumes getting back to the cab ?
dancome433 Posted July 25, 2009 Author Posted July 25, 2009 CW that was another idea, but you didnt have any issues with your spring compressing and crushin the pipe?
CWLONGSHOT Posted July 25, 2009 Posted July 25, 2009 If you can compress the suspension that far you have far more problems than just a dented tail pipe!! :roll: :brows: :yes: :yes: It doesn't even come close, so no this is not an issue. CW

CW cool, if i don't figure out another seup, I'm going to keep that one in mind,
jpnjim Posted July 25, 2009 Posted July 25, 2009 I got an offset/offset muffler (chambered Flowmaster style), flipped it on it's side, and ran a straight pipe to the back. Then popped put a turndown on the end to cut some of the noise. It might look like it hangs low, but it's just about tight to the X-member, and the bumpstops (once they go back on) hang lower than the 2.5" pipe.
ComancheKid45 Posted July 25, 2009 Posted July 25, 2009 I copied CW's setup but used a Flowtech muffler insted, i have another sitting in the garage for my XJ next
86FUBAR Posted July 25, 2009 Posted July 25, 2009 I'm running a 2 chamber flow with a 4" hole cut out and 4"turndown welded in place and its nice and loud with a good tone , if u like it loud this is it . the engine is a 3.4 v6
