The Track Edition takes all of the precision engineering and performance of its SwitchPath* counterpart, minus the driver*s side muffler and valve on the passenger*s side. The result is a constant *valve open* mode. If you're craving rich 5-cylinder tones at all times, this is your dose of steel. This version is known to get rowdy, and may be too much for many. For that reason, this particular version cannot be returned due to sound preference. Prepare yourself! However, AWE made it simple to convert to the more civilized Touring Edition if you ever feel it's too much! Just grab one of AWE's engineered Conversion Kits, and you're toned down. Easy! The AWE Track Edition comes standard with Diamond Black 180mm RS-style oval tips, complete with stamped AWE logo. AWE Track Edition Exhaust for Audi MK3 TT RS - Diamond Black RS-style Tips
