DansGreyMj Posted April 30, 2006 Share Posted April 30, 2006 my muffler cracked in half today and was wondering what diameter is the exhaust, correct me if I'm wrong but is it 2.5 Link to comment Share on other sites More sharing options...
Bounty Hunter Posted May 1, 2006 Share Posted May 1, 2006 Most jeeps are 2.25" inlet and 2.5" outlet. Link to comment Share on other sites More sharing options...
Eagle Posted May 1, 2006 Share Posted May 1, 2006 Most jeeps are 2.25" inlet and 2.5" outlet. Nope. Except for the early 4-cyl, which are 2", the exhaust systems on all XJs and MJs are 2-1/4". The catalytic converter is a 2-1/2" input, with a 2-1/2" outlet that necks down to 2-1/4" before entering the muffler. Link to comment Share on other sites More sharing options...
DirtyComanche Posted May 1, 2006 Share Posted May 1, 2006 How many 15+ year old vehicles have the stock exhaust? Mine is 2.25 I think. But I don't remember. It was pretty weird. Link to comment Share on other sites More sharing options...
Eagle Posted May 1, 2006 Share Posted May 1, 2006 How many 15+ year old vehicles have the stock exhaust? "Stock"? or "Original"? All of my XJs and MJs have "stock" exhausts. None are the factory original, but after trying a 2-1/2" turbo muffler cat-back in the XJ and suffering loss of low-end torque and a drop in gas mileage, I'm sticking to the OEM replacement stuff. Pipes are cheap, the mufflers come from Auto Zone with a lifetime warranty so I'll never buy another muffler, and the performance is back to what it should be -- what's not to like?

Pete M Posted May 1, 2006 Share Posted May 1, 2006 Stock? or Original? :D Link to comment Share on other sites More sharing options...
DansGreyMj Posted May 4, 2006 Author Share Posted May 4, 2006 I put on my cherry bomb glasspack today with a 2.5" inlet/outlet, it sound pretty good but not as good as running mufflerles the past 2 days it was so loud I'm glad i never saw a cop Link to comment Share on other sites More sharing options...
Eagle Posted May 5, 2006 Share Posted May 5, 2006 Are you doing a straight dump from the Cherry Bomb? If not, did you get a custom tailpipe or use an adapter to mate the 2-1/2 outlet to the 2-1/4" tailpipe? I've thought about doing a Cherry Bomb, but the price is about the same as an OEM replacement muffler, and the replacement has a lifetime warranty compared to either one year or no warranty for the glass packs. I plan to keep my XJs and MJs for a looooooooooong, time, so "lifetime" warrantees mean something to me. Link to comment Share on other sites More sharing options...
Eagle Posted May 5, 2006 Share Posted May 5, 2006 Stock? or Original? :D Hey! I have one that looks almost exactly like that. Mine's custom, though -- the back end of the tailpipe is held up by a specially fabricated wire coat hanger assembly, creatively adapted to the MJ chassis by a probably inebriated Rhode Islander who shouldn't have wasted his time, because what it supports is mostly air, connected by a few flakes of rust.

Apparently that doesn't cover ripping it off on rocks, though. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted May 5, 2006 Share Posted May 5, 2006 I threw on a cherry bomb when I first got my MJ!! Its nice, not too loud. Although now that its a year later...its getting a bit louder, but you just can't beat the durability and cost!! Here is a pic; CW Link to comment Share on other sites More sharing options...

Actually i meant to 2.25 in/out and i just used the old existing pipes cuz my are still in great shape i just want to get a new tip cuz mines ugly and bent cuz some dumba** parked a shopping cart in my blind spot on a rainy day and i was in a hurry to get in the car and i didnt see it, atleast there was no body damage Link to comment Share on other sites More sharing options...
bhawkin2 Posted May 6, 2006 Share Posted May 6, 2006 We have an exhauset bender at work, so we play with all kinds of mufflers an tail pipe configurations on our down time. Boss thinks it helps us learn. :brows: Link to comment Share on other sites More sharing options...

I plan to keep my XJs and MJs for a looooooooooong, time, so "lifetime" warrantees mean something to me. I had one on my XJ. But I disliked the sound. I felt it was an extremely flat sound. I did like the fact it really was very high compared to stock exhaust. But, I replaced it with the Lifetime Meritor muffler from VatoZone. But my local AZ did warranty the one crushed shut from rocks. They just said 'road hazard, huh?' Link to comment Share on other sites More sharing options...
feerocknok Posted May 7, 2006 Share Posted May 7, 2006 I had dual cherry bombs on my V-8. That's 4-cylinders a bomb and I blew the left one in two weeks! No more of those for me. Link to comment Share on other sites More sharing options...
