Doug's Headers Exhaust Pipe: Race-Proven Engineering on Every Build
When it comes to exhaust pipe components, few names carry the weight of decades of drag strip credibility the way Doug's Headers does. Doug's Headers opened its doors in 1958 as a small muffler shop in East Los Angeles, CA, and rapidly expanded into a shop that designed and built innovative exhaust products for muscle cars and many of the sport's top drag racers. That same DNA runs through every exhaust pipe component they produce today.
What Sets Doug's Exhaust Pipe Products Apart
Doug's doesn't treat exhaust pipe as an afterthought — it's an integral part of a complete, engineered system. Each product 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. That engineering precision extends directly to their exhaust pipe offerings, which are built to work in concert with their headers for a seamless, optimized flow path.
To ensure a longer lifespan and extra strength, each component is made using heavy-gauge tubing. Doug's products are CNC mandrel bent for precise fit and improved exhaust flow, and feature accurately formed long transition collectors to reduce backpressure and a polished MCTB coating to resist corrosion and heat up to 1,400 degrees.
One standout example of Doug's exhaust pipe craftsmanship is their Corvette side pipe lineup. These pipes feature 1 7/8" tube sizing, 4" collector dimensions, 3/8" flanges for leak-free performance, and 16-gauge steel construction for longer life. The sidetube mufflers come in two versions to fine-tune the volume, making your Corvette sound like the muscle car that it is.
Applications: Muscle Cars, Trucks, and Everything In Between
Doug's Headers now offers street performance enthusiasts the same exhaust system innovation that made it a drag racing legend, with a complete line of headers, exhaust systems, mufflers, and exhaust components for street rods, passenger cars, two- and four-wheel drive trucks, and more. Whether you're building a classic Pontiac GTO, a big-block Corvette, or a modern engine-swapped truck, Doug's exhaust pipe products are engineered to complement their header systems with the same attention to fitment.
- Corvette Side Pipes: The Corvette Sidemount lineup features precision-built long tube configurations for both Big Block and Small Block applications, increasing flow for maximum power gains.
- Ceramic Coating: Long transition collectors reduce backpressure, while the MCTB coating resists corrosion and heat, topped off by thick flanges, machined sealing beads, and a superior finish.
- Complete Hardware Included: Every Doug's product comes with all the necessary mounting hardware, collector reducers, premium gaskets, and detailed installation instructions.
A Commitment to Fit, Not Just Performance
Driven by the idea that the customer should only have to install the product — not modify it to fit — the experts at Doug's create parts that can be trusted for perfect fit and quality. Doug's exhaust products are carefully developed on the vehicles they are intended to fit and are subject to rigorous quality checks during the design and manufacturing process.
