The Hooker Maximum Flow muffler actually flows 99% andproduces more horsepower and torque than a 2-1/2" open pipe. The Maximum Flow is constructed of an aluminized steel case with stainless steel internal core and uses ahigh temperature packing material to absorb excessive noise while allowing a mellow powerful sound. As with all absorption type silencers, theMaximum Flow will be most effective for sound control with lower compression (8.5 to1 and lower) motors with conservative Camshafts and with applications using catalytic converter(s). The Maximum Flow flows either direction, allowing for easy installation
