Hedman 66539 HTC Coated Engine Swap Exhaust Headers
Fits 1982-2000, Chevrolet Blazer, S10, GMC Jimmy, S15 with small block Chevy V8

Hedman standard duty 66539 headers for swapping a V8 into an S10, S15 or similar GM vehicles are available from the factory with Hedman's own exclusive "HTC" Ceramic-Metallic thermal protection coating. This is an extremely durable coating that was developed by the aerospace industry and pioneered for use in automotive applications by the engineers at Hedman Hedders. It greatly improves not only the lifespan of your Hedman headers but also their function. It resists corrosion from moisture, road salts, and oxidation, and shields against heat up to 1,400 degrees! This helps to keep the exhaust heat inside the headers where it belongs, which not only speeds up the flow but protects underhood components from damage due to excessive heat.

Hedman's 66539 header is superior to your factory cast iron exhaust manifold, with its short cramped design that restricts exhaust flow. Your Hedman Hedders feature smoothly bent individual pipes that help to pull the exhaust gases out of each cylinder. Hedman's 66539 exhaust header has been designed specifically for your vehicle and will fit and perform better than any other exhaust header you can buy.
