Hedman Hedders Exhaust Header Collector

Hedman Hedders Exhaust Header Collectors: Precision Engineering Since 1954

When it comes to connecting your exhaust headers to the rest of your system, the collector plays a critical role in maintaining optimal flow, preventing leaks, and accommodating the inevitable chassis movement and thermal expansion that occurs during operation. Hedman Hedders has been engineering exhaust systems and manufacturing headers in the USA for over seven decades, and their collector technology represents decades of refinement aimed at solving the persistent challenges faced by performance enthusiasts and professional builders alike.

Ball-and-Socket Collectors: Hedman's Signature Innovation

Hedman's unique, gasketless ball and socket collector design allows your exhaust system to bolt up, even if it is not perfectly aligned with the header collector. This innovation addresses one of the most common frustrations in exhaust installation: achieving perfect alignment between the header outlet and the exhaust pipe inlet. The gasket-free collector design works with Hedman's Ball and Socket Style Header Collectors, eliminating the need for replaceable gaskets that can fail under extreme heat cycling and exhaust pressure. Available in multiple collector sizes ranging from 2-1/2 inches to 3-1/2 inches, these collectors accommodate everything from small-block street builds to big-block racing applications.

Traditional 3-Bolt Collectors and Complete Hardware Kits

For applications where a more traditional connection is preferred, Hedman's Classic 3-Bolt Gasket-Style Header Collectors remain a popular choice. Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed with the ball-and-socket design, while the 3-bolt style comes complete with all necessary hardware and gaskets. Hedman reducers (exhaust system adapters) weld on to your exhaust system, so you can easily bolt up your Hedman Hedders to the vehicle's exhaust. Available in mild steel, Aluminized steel or stainless, each kit comes with necessary flanges, gaskets (when applicable), and hardware.
