just post up your timing map from the UTEC and we can quickly tell ya how much room you have to play. if its only 13-14 degrees at the top, you can easily add another 5-6 degrees.

There is possibly a catch to all this though. My 403 whp was measured at 6800 RPM in tiptronic (slightly raised rev limit via reflash). I've been under the impression (told) that in drive, you're stuck with a hardcoded 6600 RPM limit. If that's truly the case, on any given day I may only be pushing about 380 whp, because I typically cruise around in drive.

If you want to keep the your stock tone, but still want to open it up, you should go for the Nismo exhaust with high flow cats, or the Fujitsubo (the same as the Nismo one) that Mark recommended above.

You guys think that previously posted clip of the Fujitsubo is representative of the real sound? It's on a Z, and there's something in the background, could be a dyno, or maybe even an SC.

Found one on youtube of a G35. High RPMs sound sick.
It's just so damn hard dishing out a grand for something you spec'ed out on youtube! Sounds like you guys have all been down that path before, since some of you have gotten 3 exhausts!

Measure the back pressure at various points at WOT HP peak rpm to calulate how much you are losing.
Tap new threads in exhaust to connect before and after 1st cat, then after last cat [to analyse muffler system].

Hey guys, thanks for the tip! It was like finding the holy grail, but I finally found a vendor with a fuji in stock. Fuji + vortech = pure sex. It definitely sounds different than all of the NA clips. It has a deep rumble at low RPM (*almost* like a V8), not obnoxious at all, and then at high RPMs the thing just screams, sounds like a ferrari.
