Q & A

What's in the Box

These long tube headers work with both automatic or manual transmissions in 1964-1989 Chevrolet chassis. Features 1-5/8" primary tubes, 3" collectors, and fits angled or straight plug S/B Chevy oval exhaust port heads. Built with surface machined thick steel flanges for a great seal and mandrel bent mild steel tubing. These headers are a chassis header and are meant to go inside of the frame rails on the 1965-1989 Chevrolet chassis.

Available with metallic ceramic coating. Unlike paint or chrome, metallic ceramic coating is easy to keep clean, resists rust and corrosion and will not discolor. Metallic ceramic coating also reduces underhood temperatures.

Headers come with installation hardware, collector reducers, gaskets and instructions.

  7. These headers are a chassis header and are meant to go inside of the frame rails on the 1965-1989 Chevrolet chassis.

Armor Hot Coating (AHC) is a heat resistant, ceramic coating applied to the outside of the header. This coating will reflect heat, which helps retain more heat within the header tube while simultaneously speeding up the exhaust flow. Not only will this coating help you make more horsepower, it also keeps your headers rust-free, looking great, and lasting longer (when properly maintained).  If you are looking for a show-quality finish for your headers, this is it! Our AHC will withstand exhaust temperatures of up to 1300Ëš F.

Warranties

AHC Warning: AHC coatings will burn and be damaged at exhaust temperatures over 1300 degrees. A lean fuel mixture can generate exhaust temperatures exceeding 1700-1900 degrees. If the coating is damaged due to a lean condition, the coating will not be warranted, but can be recoated for a fee.

Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.
