Well, I've had my Jeep for a few months now and I think its time to upgrade the sound. Unfortunately, I have the 3.7 so there's not much to work with. After looking through the exhaust thread, I am left more confused than before. Basically, I want to upgrade the sound/look of the muffler coming out the back ("look" can probably be taken care of using simple muffler tips, but who knows. don't really mind how it looks like underneath, just the muffler end that shows). What I was wondering was what muffler would you guys recommend to make the 3.7 sound considerably meaner? I'm 19, have no kids, and am the only one who drives the car so noise doesn't bother me. Also, I would preferably like there to be 2 pipes coming out the back (I believe it's called dual outlet). Lastly, I would be taking this to a shop to be done, so the simpler the mod the easier on my wallet. Your suggestions would be greatly appreciated. Thanks!
