Well, as some of you may know, the Jeep 4.0L Inline 6 doesn't have that great of a sound to it. I currently put a CAI on mine and it helped it sound a bit better. Next, I am going to be putting on an exhaust now that my lift is done and close to paid off. I want to go with a Flowmaster to get it to sound deeper. I would like to have it sound like a V8. Any ideas as to how I can get it to have that nice deep tone of a V8 without putting a V8 under the hood? I also would like to get some performance gains out of it because the added weight of the tires and the heavy duty suspension is decreasing my fuel economy and pick-up. I would appreciate all advice. Sorry it isn't a Bonneville.

Cam it with some headers into the Flowmasters!
