Description
Super Competition Sidemount Headers deliver the most aggressive style and performance for your early Corvette, Camaro, Nova or Firebird. Sidemount Headers are built from lightweight 18 gauge tubing. Sidetubes slip directly to the collector for a leak free seal. Hooker sidemount Headers and sidetubes come with 3 choices of coating; show quality chrome, high heat resistant black paint and Hooker’s metallic ceramic thermal barrier coating. Replaceable Hooker Mufflers are available separately in 2 different styles; glasspack and reverse flow.
