Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and MID-LENGTH tube headers for Pontiac models for decades. 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 vehicle's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.

These headers have a high temperature POLISHED-SILVER ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. Each set includes a pair of header gaskets, header flange bolts and collector bolts. No collector gasket is needed. Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.

Made in the USA

Features:

NOTE: Installing coated headers on an engine during the break-in period will cause discoloration. The use of factory manifolds or an old set of headers is recommended while breaking in an engine.
