What is the best exhaust mod for a Z51 coupe w/ out NPP? Considering the emissions regulations are strict but I think Im safe for 6 years.

I love the sound of the Corsa but am looking for a system where I can go to stealth quiet mode with a switch in the cabin

I used Corsa on my C5 and really liked the sound--I have not looked lately but they used to offer a couple of types--one aggressive and the other milder. I went with the lesser but they really sounded good. cutnout aka Charlie

Borla makes an exhaust that is a bolt on replacement for the NPP, including the 2nd set of valves. You could install that on a non-NPP car, buy the 2 extra solenoids and wire them up with a switch in the cabin to open and close them. That would vice you the "Mild to Wild" effect without having to dip into the car's electronics.

Wondering if anyone knows of a dealer or installer that could do this in the Greater Los Angeles area? If it was my old 65 Mustang I could do it but not this car...:confused:
