Hooker HK21609 Maximum Flow Muffler 4" Center In & Out Aluminized Steel
Hooker HK21609 Maximum Flow Muffler 4" Center In & Out Aluminized Steel
These 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.
