Installation Notes:
Does not fit Powerglide transmissions on Chevelles. Do not use header wraps; they can cause header tube cracking from excessive heat or rust from moisture build-up and void the warranty. Breaking in an engine with ceramic-coated headers can damage the coating and void the warranty. Use cast-iron exhaust manifolds or old headers during engine break-in to prevent coating damage. Ceramic-coated headers require several heat cycles to fully cure before withstanding extreme heat. Please call Flowtech Technical Service at 270-781-9741 for additional information regarding ceramic-coated exhaust products.
