HI, I have a 2004 Zo6, I installed the Corsa Extreme, and the X-pipe.I have driven about 500 miles, and my gas mileage is about 4 miles per gallon less that before. I would say that half of those miles were at highway speeds. Has anyone else had this happen, and is there any way to improve the mileage back to what is was. Thanks,
Marc

I highly doubt the Corsa is responsible for the drop, it's most likely since you like hearing the sound of your new exhauust so much your on it much more than usual. That's what usually happens
