never got straight answer

 

IIRC, The exhaust fits but test pipes need to be modified

 

yes all aftermarket Z exhausts remain direct bolt ons. its pretty much the ONLY direct bolt on power adder.

Once you get the exhaust please post before and after dyno graphs (dynojet)

I'm doing so for my test pipes install.

 

they fit.

 

Sharif, I know youve only dynoed a 07 Z with Greddy TT exhaust, but what do you think the difference will be with a Greddy Evo 2, think it will make more or less power?

 

good question

 

does the GReddy evo 2 come with a y-pipe linked piping?
evo 2:

TT:


the GReddy TT is true dual 2.75" with a small H pipe in between, while the evo 2 probably has a 2.4~2.5" piping (and that y-pipe, judging from the pic). in n/a form, i can see a higher peak power with the TT, while the evo 2 may induce a nicer lower to mid torque curve. if forced induction is truly a must have, i say go with the evo TT... it's a very nice system!
