Doug's Headers Gaskets and Sealing Systems

Doug's Headers: A Legacy Built on the Drag Strip

Doug's Headers is one of the most storied names in high-performance exhaust, with roots stretching back to 1958. The brand began as a small muffler shop in East Los Angeles, California, before expanding rapidly into a shop that designed and built innovative headers for muscle cars and many of the sport's top drag racers. The famous "Headers by Doug" decal was consistently found on many of the top cars in various classes during the 1960s and 1970s.

Doug has been elected to five different drag racing halls of fame and is truly a pioneer in the manufacturing of high performance exhaust systems. Today, the brand is a PerTronix Performance Brand, but the commitment that built its legendary reputation remains unchanged: Doug's will not compromise performance, quality, or fit to compete with inferior designs at cheap prices.

Engineering That Delivers Real-World Results

The heart of the Doug's Headers lineup is, of course, its exhaust headers. Each Doug's Header is designed with the proper tube size and length to efficiently scavenge the exhaust from each cylinder, reducing pumping losses and resulting in maximum increases in horsepower and torque. Doug's Headers offers Long Tube, Mid-Length, and TRI-Y Headers for passenger cars and 2/4 WD truck applications, as well as iconic Corvette Sidemount designs for 1963–1982 Corvettes.

What sets Doug's apart from the competition is their obsessive attention to fitment. Driven by the idea that the customer should only have to install the headers — not modify them to fit the car — the experts at Doug's Headers create parts that can be trusted for perfect fit and quality. Doug's headers are carefully developed on the vehicles they are intended to fit and are subject to rigorous quality checks during the design and manufacturing process.

Beyond headers, Doug's produces a comprehensive range of exhaust pipes and system components. Specializing in performance headers engineered for specific applications, Doug's also offers Stainless Steel Electric Cutouts, Weld-up Race header kits, DIY components, and accessories. Whether you're building a complete header-back system or sourcing individual pieces, the brand has you covered.

Engine swap builders will find Doug's especially valuable. Doug's Engine Swap Headers are designed to fit with many aftermarket engine swap kits, engineered for the horsepower and torque increases produced by modern engines while properly fitting the tightest engine swap applications. The brand even offers transmission crossmembers designed to complement these engine swap packages, rounding out the installation hardware you need to complete a swap correctly.

For sound control, Doug's exhaust insert mufflers and sidetube muffler options let you fine-tune the volume and tone of your exhaust note. The Sidetube Mufflers come in two versions to fine-tune the volume, making your vehicle sound like the muscle car that it is. And for maximizing exhaust flow on multi-pipe setups, exhaust Y pipes are available to efficiently merge exhaust streams and reduce backpressure.

Who Are Doug's Headers Built For?

Doug's Headers are ideal for muscle cars, street rods, and race cars, as well as trucks, SUVs, and motorhomes. Headers are available in Metallic Silver Ceramic or Hi-Temp Black Coatings, or raw steel for individual customizing. Whether you're chasing tenths on the quarter mile or simply want your classic cruiser to breathe and sound its best, Doug's Headers brings more than six decades of exhaust engineering expertise to every product they build.
