Well IMHO Mac's sound like crap...Managflow is way to quiet.SLP sucks.. Pypes sounds like your running no exhaust...Borla is ok i guess...Spintech is up there next to flows in sounding nice..So what other exhaust is really out there??![]()
while magnaflow are quiet at idle and until 2k, after 2k they scream. go to the exhaust sticky and listen to sspcoupes clip. they are also up on the list for hp numbers
