I'm about to buy a Nismo S tune exhuast system for my 07 Z, but I have heard that there are fitment issues and there are a couple of flanges that need to be modified for clearence. Does anyone know if these systems are a direct bolt on that fit and dont leak or vibrate against anything. Thanks

 

Nismo it typically a perfect fitment. The exhaust that needs modifications to the flanges and hangars to make it fir properly without leaks or rattles are the cheap knockoffs, like xo2, etc.

 

I have the s tune nismo exhaust on my 03 and it bolted right on with no problems.

 

Nismo = nissan so its oem fitment
