1-1/2 in. Short Tube; 2-1/2 in. Collector- Black-Maxx Satin Black Ceramic-Metallic Coated Mild Steel Hedman Hedders has been manufacturing quality headers in the USA since 1954. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your exhaust system to bolt up, even if it is not perfectly aligned with the header collectors. The super smooth, 1-1/2 in. primary tube design provides ample exhaust flow to help the carbureted 20R or 22R engine produce maximum horsepower. The compact MID-LENGTH design provides excellent low-end torque for better streetability. These headers have a high temperature SATIN-BLACK ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. This finish is covered by a 5 year factory warranty, in addition to Hedman's standard lifetime header warranty. Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed. Hedman Hedders is so confident in the quality of its headers that each set is factory backed by a Limited Lifetime Warranty against manufacturer defects. Includes Headers, ball and socket reducers (exhaust adapters), gaskets, mounting hardware
