Doug's Headers Side Mount Exhaust Big Block Chevy Collector

Doug's Headers Side Mount Exhaust Headers for Big Block Chevy engines are performance side mount headers (also called sidemount headers or side pipe headers). They replace restrictive factory exhaust manifolds and route exhaust from each cylinder through individual primary tubes into a collector. The outlet is built for a side-exiting exhaust. This helps the engine breathe more freely and supports gains in horsepower and torque.

Key Features:

• Side mount design: Built for applications that use a side-exit exhaust.
• Big Block Chevy application: Made for round-port big block Chevrolet V8 engines.
• Individual primary tubes: Improve exhaust flow compared with a cast factory manifold.
• Slip-fit collector attachment: Simplifies connection to the side pipe or exhaust system.
• Quality construction: Made from 16-gauge tubing, with flanges and gaskets supplied for installation as documented for each part number.
• Multiple options: The line is offered in different materials and finishes to suit different builds.

Doug's Headers is a long-time American maker of performance exhaust headers. This side mount line suits restorations, street performance builds and show cars, and it delivers better exhaust flow while keeping the classic side pipe look.
