Kuryakyn torque cones are designed to create a back-pressure while accelerating the exhaust gases through the pipe to avoid resonance. Long rides are more pleasant with the cones installed because the engine has a more constant response. Smooth out your power curve to provide a more consistent performance—and recover some of that lost horsepower and gas mileage without affecting the sound. Torque cones are available for a variety of Harley-Davidson® bikes from 1984 and up.

Hooker Maximum Flow mufflers allow 99 percent more exhaust flow and produce more horsepower and torque than a 2 1/2 in. open pipe. They're constructed from aluminized and stainless steel and use high-temperature packing material to absorb excessive noise, while allowing a rich, low-toned sound. As with all absorption-type silencers, the Maximum Flow mufflers will be most effective for sound control on lower-compression (8.5 to 1 and lower) motors with conservative camshafts and on applications using catalytic converters. The Maximum Flow mufflers flow either direction, allowing for easy installation.

Improve your exhaust flow by 23 percent with Hooker Aero Chamber mufflers. They are designed to do much more than simply muffle exhaust noise; they produce a deep throaty rumble that will not change--ever! Plus, Aero's aerodynamically designed chambers flow better to deliver more horsepower and torque thanks to their unique step principle. The stepped acceleration chamber increases exhaust gas velocity for maximum flow. An aerodynamic lens directs sound pressure into and out of the muffler while resonance chambers and sound absorption chambers create the sound. And, to keep Aero Chamber mufflers from rusting from the inside out--a stainless steel perforated plate to eliminate internal rust. Muffler cases are available in 16-gauge aluminized steel or stainless steel but it's truly what's inside that makes it so sophisticated. Need a muffler? Go with Hooker Aero Chamber mufflers--the real master of flow!
