I just bought a F4i and i'm wondering if there are any tests done on them or if anyone knows what is the best or best sounding. Preferably most performance and lightest weight. This includes high pipes or undertail pieces.

 

well, the difference is negligible. as far as sound, totally subjective.
in general, the regular mounts would yield more power than the high mounts as there is less bends involved.

for reduced weight, get at ti or cf can...and if possible, ti midpipe.

 

i have a full micron with race header and love the way it sounds and performs

 

Two Bros. sounds sick! I've got the C2 Carbon Fiber. Standard mount.

 

i second that. they've got a sound file on thier website. will more than likely be my next purchase after suspension tuning.

 

Got an akropovic c/f ti dude its awesome. Highly recommended

 

i have a D&D and it sucks. it sounds like a V6 mustang with a magnaflow exhaust.
i want a Blue Flame , i <3 the way it sounds like an F1 car or the Yoshi
