What a great system! Goes in easy, parts fit right, and when its fired up, oh boy, it sounds great! Put about half hour run time on it today, it still sounds nice. It is louder than I expected when accelerating, but I'll get used to that. Quiets out nice when cruising, but you can still hear it.

One thing I don't like about it is the length of the tail pipes. They just stick out too far, and don't look like something Pontiac would have done. Will probably end up cutting 2" off the ends of the tail pipes to bring them in a bit, and get shorter rubber hangers for the rear to raise the tail pipes about 1.5 ".
