3" Front Pipe Back Exhaust - Explorer ST

From the front pipes all the way back, the 3" tubing creates a more aggressive, higher flowing exhaust. A deeper, throatier sound, and the same True Helmholtz Technology to eliminate drone.  The front pipes connect after the catalytic converters and do not alter the OE emissions.
