In my 02 hooker max flows are far better. There cheaper and come painted to fight off rust where the standard flowmasters rust in a few months depending on where you live. The hooker max flow is made to be quiet during idle and crusie and a nice crisp sound during accel. its also a strait thru muffler which keep the gases flowing (velocity up) instead of a flowbastid that decompresses the gases to move around bafflers further hurting flow and velocity to recompress to exit the muffler back into a pipe (bottle neck)
Or any other strait thru like magnaflow, glass pack, dynomax ultras, bullets....
