I have a Kooks catted H pipe which I used for less than 400 miles for sale.
2005-2006-2007-2008-2009 Mustang GT Kooks 2.5" Catted X Pipe - For Long Tubes
Kooks X Pipe consists of 2 1/2 inch piping, and utilizes high flow catalytic converters. This can integrate into your OEM system, but best performance gains are achieved when used with Kooks Long Tube Headers.
They are as close to new as possible without being new. I switched to off road H pipe. It cost me $550 and I am selling for $450 plus shipping. I doubt you'll find a better deal anywhere. Part # 6023-CH
