What are some inexpensive options for exahst on the V. Id like to make it a little louder than stock with more power. I was thinking about just x pipe which im told replaces the cats
but im not sure where i could get this or if it is possible. If anyone has any other ideas please tell me. Any advice will help.

 

A good muffler shop can replace the factory resonator with an x-pipe. I've heard one and it sounds a bit nicer, and if I recall correctly you might pick up a few ponies in the process.

Did you check out www.cadillacfaq.com?

Go to the CTS-V index, under engine and exhaust, page two.
