Well i just got an 04 crew cab super duty powerstroke, and i love it!! But now im ready for mod # 1, Exhaust. I want the loudest exhuast possible, without doing a straight pipe. a friend of mine has an 03, and im not sure what kind of exhaust, and it sounds like a jet engine. What exhaust system can i do to get my truck that loud? the louder the better, thanx for the help.
