Replacement Muffler - 1990 YJ 4.2L ??
 

Greetings!

I'm replacing the tail pipe and muffler on a 1990 4.2L Jeep Wrangler.
I've ordered a replacement exhaust pipe from the local auto parts
store, but I wanted a muffler with a little more attitude than a stock
replacement. The existing original muffler is 13" long, with a center
2" inlet and an offset 2.25" outlet. I can't find any aftermarket
muffler that matches these dimensions. Has anyone encountered this and
found a solution?

Thanks!

Generally folks buy a cat-back system that replaces everything from the
catalytic converter back to the exhaust tip. But since you got the
pipe your options are limited to OEM unless you want to do some
fabrication yourself or have a muffler shop weld one in for you.

Your basic muffler shop can put anything you want in there. I'd stay
away from glasspacks (too loud for most folks) Thrush, and just about
any other aftermarket can be made to fit, except possibly the Gibson
as it's much longer than stock.

i ran one of Rusty's cat-back exhaust systems on both my XJ and YJ and
felt that they both gave a nice boost of power and a great 'growl'
effect when i stepped on the gas. check out Rusty's Offroad under the
performance section http://www.rustysoffroad.com

good luck!
