Hooker Headers, Aero Chamber Muffler

Look inside all other mufflers and you'll find simple glass packing or welded plates. Look inside Hooker's Aero Chamber and you'll find the most sophisticated muffler available.

The Aero Chamber muffler is designed to do much more than simply muffle exhaust noise. The Aero Chamber muffler produce a deep, throaty, powerful rumble that will not change, ever! Plus, Hooker's aerodynamically designed chambers flow better to deliver more horsepower and torque thanks to Hooker's 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. The aerodynamically designed chambers flow as much as 23% better and produce more horsepower and torque than the most popular high performance brand.

And, to keep Aero Chamber mufflers from rusting from the inside out, a stainless steel perforated plate to eliminate internal rust. Muffler cases are 16-gauge aluminised 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!
