Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and mid-length tube headers for 2nd Gen F-Bodies for decades, so designing a good fitting, great performing set of headers for the popular LS engine swap. Each set uses smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. The stout 3/8" header flanges ensure a great seal that will resist warping, and Hedman's unique, gasketless ball and socket collector design allows your Camaro, Firebird's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors. Hedman is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. The tough, polished silver HTC ceramic coating on these headers is good up to 1400 degrees. It helps keep underhood temperatures down, and prevent rusting of the headers. Unlike chrome, this finish will not "blue" or discolor. The coating is warrantied for 5 full years.
