LS Conversion Exhaust Header Set, Mid-length, Black Ceramic Mild Steel

LS Conversion Exhaust Header Set, Hedman Street, Mid-length, Black Ceramic 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. The tough Black Maxx matte black ceramic coating on these headers is good up to 1400 degrees. It helps keep underhood temperatures down, and prevent rusting of the headers. The coating is warrantied for 5 full years.

Note:

Fit round cylinder port stock profile heads. 4L80E requires modification / trimming to bellhousing ears.
