Yeap, check my sig. I did a review of this awhile ago; the post is somewhere in the archives.

IMO, it's pretty pricey but for just simple bolt-ons it's top-notch quality. Comptech says 20 whp gain on a 2000 gsr, but I don't trust their dyno-plot. If you combine I/H/E with a hi-flo cat, 15-20 whp isn't too far fetched.

The comptech icebox is noticeably louder at 6000+ rpm; the thinner walls of the header make engine noise a little more discernable at lower rpm. The car cruises along with a nice low hum; really noticeable in parking lots when you're in 1st @ 4000 rpm trying to find a parking spot h: Overall I love the sound.

I definitely felt a power different at middle and higher rpm; right off the line the car would have a tendency to bog a little more but that might be unrelated.

My only gripe would be the generic look of the exhaust tip/muffler, but if you're going for the sleeper style then it works well.

I really need to scan pictures of my car with the LE's on them.....
