I was checking under my 09 C6 the other day and noticed it has a factory X pipe. Someone told me it comes standard with NPP. Is this true or do they all have the X pipe now.
Thanks
edited to add: Now I know where I read it. The new Motor Trend has a write up on the Grand Sport.
Quote " The burble and snarl of the X-pipe dual-mode exhaust system (base cars get a H pipe) seems worth every penny."
The article is full of inaccuracys including ALL GS manual cars get the dry-sump oiling system.
Edited to add: MT also states the GS has a close ratio tranny. I know it has a little different gearing but it has a wide ration tranny compared to the base car.
