Elliot Chevy 4-Into-1 Headers for Demo Derby – SBC | 30″ Tall
The Elliot Chevy 4-Into-1 Headers are widely considered the gold standard for Small Block Chevy demo derby engines, delivering a crisp, clean exhaust tone that roars under throttle while maintaining the durability required for hard-hitting derby competition. Built specifically for SBC demo derby applications, these headers combine proven exhaust flow, rugged construction, and a sound that separates serious builds from the rest.
Designed to fit Small Block Chevy (SBC) V8 engines, these demo derby headers feature a tight 4-into-1 configuration that promotes fast exhaust evacuation and consistent performance during long heats and repeated impacts. The 30″ tall header design keeps exhaust high and protected in the engine bay, reducing the risk of damage from front-end hits and engine movement.
Primary Tube & Collector Options
These Elliot SBC demo derby headers are available in two primary tube sizes to match your engine setup and power level:
- 1.5″ Primary Tubes
- 2.75″ Diameter Collector
- Ideal for stock and mildly built Small Block Chevy engines
- 1.75″ Primary Tubes
- 3″ Diameter Collector
- Designed for higher-output or more aggressive SBC builds
- Both options feature an 8″ tall collector for consistent sound and exhaust transition
Built for Demo Derby Abuse
Each header is constructed using aluminized steel primary tubes for excellent heat resistance and longevity. A 3/8″ thick round-port steel header flange provides a strong, leak-free seal at the cylinder head—critical for maintaining performance in the harsh demo derby environment. The result is a header that delivers strong exhaust flow, long-term durability, and a sharp V8 exhaust note every time you hit the throttle.
