Exhaust Manifolds VS Headers | How Much HP Do Headers Add

Headers and manifolds differ in design and function. Long tube headers, shorty headers, and exhaust manifolds each have their pros and cons regarding performance and application.

Exhaust System Header Wrapping

Whether you’re looking for performance improvements or heat reduction, if you decide to wrap your headers, we'll show you the benefits and possible precautions to take before you wrap your exhaust.

Tuning Tips after Header Installation

Making the switch from manifolds to headers is a popular performance upgrade, but it may take more than just bolting on the new part. We provide some tips and things to consider after you bolt on a new set of headers.

Hooker Header Installation Guide

Hooker headers are installed in a 1967 Pontiac Firebird for increased power and a boost in performance. See how to work through fitment of the steering box, clutch Z bar and starter.

Ceramic Coated Headers

Watch our video on the ceramic coating process for Armor Hot Coating. Headers coated with Armor Hot Coating protect your car without sacrificing looks.

Exhaust Repair

Some basic info on the various exhaust options carried by Speedway Motors.

Replacing GM Rear End Spherical Bushings

In this budget build, a GM rear end is upgraded in order to hold 400+ HP. See how spherical bushings are replaced in a used 8.5” GM 10 bolt rear end.
