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. Note: 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.
