Thanks for the update. I will probably purchase the Berks HFC. I did some more research on the Invidia Gemini Exhaust you installed, OMG that thing is nice. I just can't believe how polished and high quality the exhaust is for less then $1,000.00.
I have a Black 370z as well, how do you like the burnt TI tips? That is the only thing I am on the fence about, but it probably looks pretty good on black.
