Product Details

Hedman Headers offer excellent exhaust flow, reduced back pressure and improved performance. Includes hardware, 3" collector to 2-1/2" exhaust reducer, gaskets and instructions needed for installation. Tests have shown a 1.1 second improvement in 0 to 60 second times.

New mid-length headers provide maximum ground clearance for lowered trucks and allow exhaust pipes to be tucked so they don't extend below the frame rails.
When installing #36-6010 it is necessary to cut existing lead pipe to attach new header adaptor pipe that is included with Header Set. When installing #36-6020 it is necessary to fabricate your own lead pipe to complete installation. Headers are painted black.
