Tell them not to waste their time on an exhaust, especially not one that they will charge $2k for. The VQ motor is not one to take to bolt on's very well. Everything is designed so well from the factory that aftermarket parts dont gain much power. They are mostly for looks, sound and bragging rights.

You seem to be putting a lot of faith behind this. I'd be weary of putting so much hope for those HP numbers.

I love them!!! It was like night and day you felt a little more umph and the growl didn't hurt either. Maybe cause thier mine but I think it sounds better then my friends stillen short tubes. I just hope when I put on my exhaust and and HFC that it wont take away from the intakes to much.

RIght after the cats the Y pipe is 1.75 then i think it goes back to 2.5 as the y pipe meets and then back to 1.75 after the resonators.
