I have a stock 2000 SS Camaro w/automatic. I am gonna change the exhaust and cant decide if I want the Gmmg catback. The Ls1sounds clips of the Gmmg sound awesome, but how loud is it in the car cruising and at highway speeds. (drone) I will eventually get headers, cam, and a catted y pipe. There arent many camaros in my area to checkout or listen to in person. I am not dead set on the Gmmg. Thanks for your help and/or recommendations.
