About this product

Part #: 21601HKR

The Hooker Maximum Flow muffler actually flows 99 percent and produces more horsepower and torque than a 2–1/2 inch open pipe. The polished stainless Maximum Flow is constructed of all stainless steel for maximum corrosion protection, good looks and long life. They use 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.

    About Hooker

    The Hooker philosophy is simple - make real, useable power by balancing the intake and exhaust pressure waves. This efficiently expelles all the burnt gases while drawing in the maximum fresh charge of fuel and air. The Hooker team will sometimes spend twice as much time developing a header to find better performance. Hooker Headers - Do It Right The 1st Time.
