    Hooker Headers Sidetube Slip-In Mufflers are designed specifically for vehicles with 4'' diameter sidepipes. They are constructed using 16-gauge aluminized steel for durability and can be removed easily for racing.


    Available in three core styles to suit your sound control and performance needs:
    The reverse flow design for small and big block engines does not restrict engine efficiency and has the highest level of sound control for the quietest possible configuration.

    The glasspack design has greater flow capacity & is louder than the reverse flow mufflers. They produce that classic 1960's performance sound.

    For 1965-74 Corvette applications, the maximum flow design has a straight-through, high-flow perforated core that operates at 99% efficiency with average power gains of 23% over open headers. Testing on a 1968 Corvette with a 427 engine yielded an increase of 40 horsepower and 20 ft/lbs of torque, which is more than an undercar exhaust with turbo mufflers.
