Downswept BBC Dragster Header 2-1/4in to 2-3/8

The Downswept BBC Dragster Header 2-1/4in to 2-3/8 is a specialized exhaust manifold designed specifically for big-block Chevrolet (BBC) drag racing applications. It is engineered for maximum scavenging and low-end torque delivery, making it an essential component for serious bracket racers and weekend warriors who seek reliable performance on the strip.

This header features a downswept design that effectively directs exhaust gases away from the engine bay, helping to reduce underhood heat and enhance driver comfort. Constructed from heavy-duty steel tubing, it includes mandrel-bent primary tubes that minimize turbulence and maintain optimal scavenging velocity across the RPM range. The stepped primary design transitions from 2-1/4 inches to 2-3/8 inches, balancing backpressure and flow efficiency for improved performance.

Ideal for BBC-powered dragsters, altered coupes, and competition vehicles, this header is built to withstand the high-load conditions typical of repeat drag passes. Its robust construction ensures structural integrity, making it a reliable choice for those who push their vehicles to the limit. Installation is straightforward, requiring standard exhaust system integration and clearance verification.
