The flow pattern inside is slightly differnt, no real differnce the say more flow but same sound i bet most people could tell the differnce
Straight pipes are more fun..but when you live in a an area full of super old people they dont like you working on your car while its running at 11pm, guess the police dont either.
forgot about the city life hat to rub it in but ... ... ...... ... ... ... ... .... ya gotta love livin in the middle of no were
last summer i was ridding it with any exhaust just manifold and just to see the old man on the street nearly having a heart attact when I give a little more presure on gas wish I had a camera
if ya have a V8 get a set of hocker headers and a set of purple horney muflers man thoes things are loud on a 302
Just have to but in with my .02 Not to step on any toes, but Not only do flowmasters sound a lot better than straight pipe, but in a well designed exhaust system, they will actually outflow straight pipes. (in most street type applications).
just to know what are you thinking about this exhaust configuration: hedman 8300 headers 2 1/2 tube ractive x-pipe 2 flowmaster 40 serie and chrome tips just for the look
