The best setup, is MINE!!! Would like l/ts but... I have shorty headers, O/R X-pipe, and SLP LM1s. I love it, it is pretty loud at times, but cruising along in fifth isn't bad. The prochamber I believe has all of the exhaust converge in the middle, with no specified path like the h or x pipe has. Definitely check out as many videos as you can and decide which exhaust is best for you. It took me a while before I got it to how I like it. I didn't spend nearly as much as some people do, when their trying to find "the" sound for them.
