My G35 already has a Borla exhaust system with Crawford high flow cats. If/when I install some B&B headers or Stillen headers, should I expect a different sound to the exhaust or will it pretty much sound the same?

Thanks,

Jeff

 

Any change to the intake or exhaust system with moves more air through the engine will make the exhaust louder, but the overall tone will remain similar.

 

Youll notice a bubbling sound when downshifting and decelerating in gear.
