I really want to get Nismo but will consider getting greddy sp2 or apexi ws exhaust. I want something that's not too loud but similar to the Nismo. Just want to see if anybody have either of these two exhaust and what their opinions are.

 

Check out the APS 2.5" catback. I just got it and am really please. A little deeper in normal driving conditions but really wakes up at WOT. The compare the sound to a Porcshe 911. At least worth a look

 

I have the Greddy SP2 On my 07 VQHR and it sounds bomb. In normal driving its really calm and mellow but when you open up the throttle and screams to red line, I really like it.
