Thank you Elvis66. It is the Borla s-type full catback #140-726 for the ZL1. Not sure if an SS takes a different kit. The system comes bare stainless steel. I had the catback and factory cats ceramic coated as well to match. The cat back is ceramic coated in two different colors. Silver for the front section/factory cats and black for the rear section. I did black to make the mufflers and tailpipes less obvious and the black does not require to be baked on. Baking the tail pipe sections would damage the return springs that operate the exhaust valves. The actuators open the valves but the spring to close them is part of the tailpipe.
