thanks siles, i've always liked the greddy one. Thats the one i am most likely going to buy

 

Well if the HKS exhaust adds 10 rwhp like their dynos claim, then I think it could very well be worth the $1080 that we can get it for right now with lexus-part's CL discount.

But now I'm not quite sure what to believe about the sound it makes, though... I can't imagine that it's not any different than the stock exhaust based on those videos and some of the feedback I've heard. It sounded pretty impressive to me.

Has anyone else heard it first hand?
