Sound advice...I'm inclined to go the Smitty route...in fact, I WILL go the Smitty route. One more question, is an 'h' pipe necessary to tune the exhaust or not? I was thinking of running the two pipes from the headers side-by-side into two Smittys or would it be better to collect into one main pipe and then into one Smitty. Seems like the second would be more restrictive but eliminate the tuning issue if there is one. Thanks. Any recommendations on who sells the cheapest Smittys?
