Im tore between these two exhausts.
Greddy evo 2, Nismo S-tune.

WHich is the better?
I want a mild tone, not too loud, decent gains.

 

I put the EVO2 on my Z about three weeks ago and it sounds great. Deep and aggressive sounding but not loud. No rasp or drone. True dual exhaust and good gains that can be felt.

I got it from Darren at i-m-racing.com.

 

I like the Nismo sound and looks much better than the evo2, but the evo2 should give you a much better gain.

I would pick evo2.

 

Both sound good, but I would choose the greddy over the nismo for the following reasons:

1.) Nismo looks very stock. The evo2 has a more 'muscular' look to it since it opens up the rear under part of the car -
2.) Nismo sounds stock, but louder. The evo2 alters the exhaust note to a deeper tone and will not be too loud. Even with headers and test pipes, the car will be very tolerable as a daily driver.
3.) The Evo2 is freer flowing - does this translate into gains? who knows?

 

I installed EVO2 about a month ago and it definitely has a much deeper sound. My wife has an FX35 which virtually has same engine and exhaust as the Z and I'm very glad I installed the EVO2 since it sounds deeper and more "substantial" her car. I also think it looks much more aggressive. Here is a link to my pics.

Good luck!

 

I have the nismo and it has incredible build quality also wont devalue your car and it gives the best NA gains around imo; no torque loss like true dual.

 

Greddy won't lose torque since it uses an X-pipe in its design

 

Alright, evo 2 it is!
