The Hooker Maximum Flow muffler actually flows 99% and produces more horsepower and torque than a 21/2" open pipe. The Maximum Flow is constructed of all aluminized and stainless steel and uses a high temperature packing material to absorb excessive noise while allowing a mellow powerful sound. As with all absorption type silencers, the Maximum Flow will be most effective for sound control with lower compression (8.5 to 1 and lower) motors with conservative camshafts and with applications using catalytic converter(s). The Maximum Flow flows either direction, allowing for easy installation.

To use as replacement on Mustang, cut off inlet/outlet pipes flush with stock mufflers and weld in place. Stock hangers must be welded to new muffler.
