"The performance gains were felt immediately, the stock exhaust felt constricted compared to this, the flow is smooth and wide open. The only thing is getting used to the tips (which are massive) and on they kind of stick out from the sides bout fit clean and tight, and I actually like the look now its just intimidating. The sound is a deep and nice tone, and can open up into a growl and toned roar when you gun it--don't expect a throaty sound. love the system, easy to install, great performance, good look, and great quality (slammed one on a bad exit and it left a penny size dent)" posted by: gonzo on February 5, 2009
