Same thing here. I have the std. 4.0 exhaust with cat. conv. and stock muffler. I've been wondering how it would be to remove everything from the cat on back and just having a turbo muffler or a good old "cherry bomb"
The local Jeep expert said that's one of the best things you can do, especially with an aftermarket cold air intake I have.
I have a few exhaust pieces I've been collecting for the job and I'm just waiting for the time and will power now.
Any good words of advice would help.
