Exhaust Port Torque Cones for Harley Davidson Big Twins and Sportsters

Exiting exhaust gasses are sometimes pulled back into the engine by descending pistons before the exhaust valve gets a chance to close. This can contaminate the mixture of fuel and clean air and significantly reduce engine performance. Torque cones help the exiting exhaust gasses to speed up using the venture effect which stops them from being sucked back into the engine. This can help improve power by increasing the exhaust gas velocity. Great for use with unbaffled exhaust that requires some type of back pressure to run right.

  • Fits all Harley Davidson Evolution models, all years and Twin Cam 1999-later
