3" Front Pipe Back Exhaust - Explorer ST *** w/ New Dual Tip Design***
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.
