About Percy's High Performance
Percy's High Performance is a product line of Taylor Cable Products Inc., founded by racers with a singular mission: develop innovative, problem-solving products for the racing and high-performance automotive aftermarket. Since its inception, Percy's has earned a devoted following among engine builders, track racers, and street performance enthusiasts who demand parts that can survive the punishing heat and stress of high-output engines.
What truly distinguishes Percy's from the competition is their relentless focus on engineering solutions to real-world problems. Rather than simply repackaging existing designs, the brand has pioneered proprietary technologies — most notably their multi-layered Seal-4-Good and XX Carbon gasket lines. These gaskets and seals are built using a combination of "dead soft" aluminum, stainless steel, and 100% carbon felt on a steel core — materials selected specifically for their ability to conform to imperfect flange surfaces and hold a seal where others fail.
At the core of Percy's reputation are their exhaust header gaskets, engineered to withstand sustained temperatures exceeding 2,000°F. Unlike traditional paper or composite gaskets that degrade after a single use, Percy's multi-layer metal gaskets are designed to be fully reusable — a major advantage for builders who frequently tune, swap headers, or push their engines hard on the track. This reusability translates to long-term cost savings without any compromise in sealing performance.
Beyond their flagship gasket technology, Percy's offers a complete suite of exhaust system components. Their exhaust headers and exhaust pipes are engineered to complement their sealing products, ensuring a tight, leak-free system from the port face to the collector. Completing the package, their exhaust manifold bolts and springs provide the clamping force and thermal compensation needed to keep everything secure under extreme heat cycling.
Percy's approach — identifying problems throughout the industry and engineering dedicated solutions — has produced a product catalog that spans everything from collector gaskets to bung-and-plug kits and jet extensions. Whether you're building a weekend bracket racer or a serious street machine, Percy's High Performance delivers the kind of race-tested reliability that has made their products a staple in engine bays around the country.
