U will get rasp 4SURE if u were 2 feather da throttle at 2500RPM and let go u will hear da rasp... Ima have my test pipes with da GREDDY Ti-C I've always trusted GREDDY I had da Ti-C dual on my 350zHR

YESSS! glad to hear a good reponse from another person with the same pipes! so they sound really good at top end? ..because I also just bought the R-Line exhaust from AAM. so that exhaust and the resonated pipes should sound pretty good?

I got resonated test pipes from GTM and I love em... Specially da TOP END Ohhhh man
