    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.

  • Fits 4" Sidetube Systems
  • Long Lasting
  • Easily Removed for Racing
  • Will Not Restrict Engine Efficiency
  • Sold in Pairs

    Rated 4 out of 5 by from Perfect sound Bought these to be stealthy leaving my neighborhood in the morning but still be as obnoxious as need be for hostile takeovers on the street. Wish they would have payed more attention to packing for shipping though. Nothing a little controlled hammer work on the flanges couldn't easily fix. Good stuff, fast arriving, no real complaints otherwise.

    Rated 5 out of 5 by from Great Sound - Great Performance! Bought those for a set of Maximizer Side Pipes and they fit completely tight with no rattles and the sound is GREAT! Performance is also excellent, not much different than open pipes.
