I've seen on the net some few things to mod a G35c. My question is: How come there is almost no dyno numbers anywhere before the Stillen CAI and after the installation? Also before and after numbers for the complete exaust with catbacks!?

Anybody know how many HP's each mods gives?

Yes, I am a little bit "performance oriented" but don't tell me "Go get a 90 Mustang and mod it", I'm looking for the G35c, but want to mod it without adding a turbo or a supercharger and before buying the car, I want to know what might be possible to do.

Thank you,

Sylvain
