SuperMAXX Stainless Long Tube Headers are an excellent way to bolt on 16 hp and 16 Ft. Lbs. of Tq. to your 2005 - 2013 C6 Corvette.

Fits with automatic or manual transmissions and takes about 4-6 hours to install. Comes complete with a detailed, full color instruction manual for easy installation. O2 Extension cables, triple layer stainless steel gaskets, header bolts and all installation hardware are included.
