When on the gas it gives great deep sound 100% worth it

I opted for the down pipe with the cat. Everything fit great. I was pretty surprised actual. Very well built. I also bought the clamp with it and it made it an easy install.

Installed this on my 96 Bonneville. Had to change my exhaust manifold to a 97+ for it to connect properly. After that short ordeal, it fit right up with my stock exhaust and 02 sensor fit right into place. This piece is built like a work of art and flows and sounds great. Highly recommended purchase for your 3800.

Rear o2 **** not equipped on the pipe as pictured. Pipe reducer on the end not compatible with existing exhaust. 4" needed to be removed to allow for fitment to existing exhaust size as well as o2 **** location. Was able to make it work with minor modification but may be difficult for someone without fabrication equipment.

Good quality and not to expensive
