I want to know some g35 coupe driver opinions on the exhaust sound ? The Stock sound is awesome and when it hits about 4rpms its pretty amazing. I like that sound it makes too when it is dropping like an open/close noise of some sort tough to explain but if you have really stood behind it you can hear it. But i also want to make it a little louder i have read a lot of old forums about CAI's because thats what i am thinking of doing and I just wanted some opinion on that too if its worth it to get that to get it to a louder sound or is adding a CAI make it even louder at all.

Injen CAI does make it louder, it also makes a whistlin' sound when throttle is open, sorta like a mini turbo...=D

 

Do you think the Stillen Big Air Intake would make that sound to and help the exhaust with the sound like the Injen?
