Hooker Headers Aero Chamber Mufflers

Product images may differ from actual product appearance.

Hooker engineers have integrated the latest in race header design into their Aero Chamber muffler. By utilizing the step principal (various transitions in cross-sectional area), they are able to manage the exhaust pressure waves of each cylinder to enhance combustion for more power. In fact, dyno tests with a 406 c.i. SB-Chevy have proven that Aero Chamber helped produce 5ft./lbs. more torque than 2-1/2'' open pipes! Constructed from aluminized and stainless steel for long life and excellent durability.
