GMC K15 Performance Exhaust Products

Upgrade your vintage muscle car’s exhaust system with a Thrush Turbo Header Back System. Featuring Thrush Turbo mufflers with reversible flow chambers, spun-locked heads and aluminized construction, it has everything needed for installation.

Developed from our Top Ten race muffler lineup for use on the street/strip, the Super 40 features Flowmaster’s Delta Flow technology. It’s larger case profile provides the best of both worlds of performance and sound, especially on forced induction and high horsepower vehicles. The Super 40 has that deep powerful sound of the Original 40 series but with all the benefits of performance and low interior resonance from the Delta Flow technology. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.

Manufactured from high-temperature steel core/graphite faced exhaust material. Expanded steel core provides stability and maximum torque retention to eliminate gasket failure. Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head. Conforms to and seals minor surface irregularities. High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load. Can be trimmed if necessary for modified port applications. For original equipment replacement, high performance street, drag race and oval track use.

FLOWTECH understands that when you purchase a set of headers, a muffler, or even an entire exhaust system, you want to know that you’re getting everything you need to complete the installation. That’s why we pride ourselves on our installation kits, which include all the gaskets, hardware, and fasteners, necessary to hook up your headers, mufflers and/or tailpipes or side mounts in minutes. But what happens when you’re doing a custom installation, or if you want to do a show-quality job with no compromise in quality, fit or finish The answer is a complete line of reducers, brackets, and emissions accessories, all precision-engineered by FLOWTECH. These installation accessories will turn your FLOWTECH system header installation into a work of art that looks as good as it sounds and performs.

This Spectre Alternator Bracket Kit was designed for 1969-1986 Chevrolet Small Block engines with a long water pump. This triple chrome-plated kit includes two brackets and the hardware needed to mount your alternator in a clean and professional way.

“Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16″” machined flanges, with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available.”
