SuperMAXX Stainless Long Tube Headers are an excellent way to bolt on 36 hp and 25 Ft. Lbs. of Tq. to your 2010 - 2014 Camaro. Although a tune is recommended, these power gains were before the tune!

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.
