Tucker SuperTrapp® Stout Slip-On Mufflers, 624515 Pipes

4″ chrome-bodied units feature a pre-installed billet aluminum end cap, newly shaped inelts that flow better into the O.E.M. head pipe (as well as SuperTrapp True Dual Head Pipes.) The Harley-Davidson 10-19 models feature a newly designed tapered core that provides the absolute smoothest, broadest spread of hp (+9.3) and torque (+10.5 lb-ft.) right off idle and pulling well into upper RPM range. These Stout Slip-Ons measure 95.6 dB (per J2825 standard – stock is 93.2)
