    Manufactured using lightweight mandrel bent 18-gauge tubing, Super Competition Sidemount Headers offer the most aggressive style and performance for your 1963-82 Corvette!

    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.
