    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.

    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.

    I know that these Hooker Header slip-in mufflers are for a 4 inch side pipe, but what is the inside diameter on both ends of a slide-in muffler?

    Asked by: SOJS
    The ID of these mufflers will be approximately 2.5"
