Softail Thrashin Anti-Reversion Exhaust System M8 Brushed Finish TSC-1961-0
Designed for 114 and larger cubic inch, high performance engines. Baffle has a 2 1/2” inlet stepped to 2 3/4” with a reduced exit to 2 1/2”. This is a high flow baffle that produces superior low/mid-range torque without sacrificing top end power. Aggressive crisp and snappy sound with the signature 'Dog Ball' higher RPM note.
This true performance stainless steel pipe starts with square cut head pipe spigots which promote a smooth transition from the exhaust port to head pipe with a true .625" inside diameter. Eliminating the choked-up transition and mushroomed gaskets common with most exhaust systems.
Jim Feuling's patented head pipe AR Chambers® are placed at the transition from 1 3/4" to 1 7/8". Our performance merge collector has a exit AR Chamber™ into the 2 1/2" muffler inlet. The optional 'Dog Ball' baffle absorbs high pitch frequencies, producing a unique deep tone while minimizing the effects to column inertia through the muffler. All Thrashin® baffles are wrapped in replaceable stainless-steel wool and high temperature fiberglass, providing extended life packing while minimizing muffler discoloration. The exhaust exit is capped off with optional styles of reverse end cones and ID sizing to meet your engines demands and personal sound preference.
These combined features reduce gas flow resistance, back pressure and aid in the elimination of reversionary effect. DESIGNED AND MADE IN AMERICA.
Thrashin® recommends using square cut or crush ring exhaust gaskets and having your motorcycle properly tuned for best overall performance and pipe longevity.
