LS Conversion Exhaust Header Set, Mid-length, Uncoated Mild Steel

LS Conversion Exhaust Header Set, Hedman Street, Mid-length, Uncoated Mild Steel, Includes Gaskets, 2 1/2 inch Reducers, and Hardware

LS Conversion Exhaust Header Set, 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 1/2 ton Chevy/GMC'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.
