I already have the Flowmaster American Thunder catback on my 2001 and want to put a good high flow pipe on now. What is going to sound more like the old 5.0's with offroad and flows, X or H? And what is flowmasters loudest 2 chamber, the American Thunder catback isnt that loud and the mufflers are freaking huge, I think there is a different 40 series that is louder than what i have.
So anyways, I know that BBK,Dr.Gas,Bassani,and MAC all make pipes offroad or highflow, which one has good converters and fits good? And what about the flowmasters?
