You will definitely see a loss in low end power from it.

That is too much exhaust for N/A
Just ge the EVO2, it is a great sound and is cheaper...
You will also have a gain from it, not much but it will be there

The size and length of the primaries and collector in exhaust design is the most important thing. After the collector, the exhaust should really be as big as possible--that is the simple version. Here is an example of a evo tt making +10hp on a vq35hr, I've seen it make almost that on a vq35de

....how are you guys coming up with these assumptions, i've seen two dynos of stock Z's with the greddy TT exhaust and they have improved down low all the way to redline.

The Greddy Evo TT exhaust is 2.75" in diameter. The HKS Hi-Power is 2.36" in diameter. If a turbo kit ever comes out for the 07's, i'm def gonna get a hold of one. I'm going to make a decision between these two. I don't think .4" increase in diameter could make a power loss on my HR while i'm still NA....what do you guys think?
