Hooker Super Competition Header Reducers

Hooker Super Competition Header Reducers are purpose-built components designed to deliver a clean, efficient transition between performance headers and downstream exhaust systems. Available in multiple configurations to accommodate a wide range of header collector setups, these reducers are engineered to meet the demands of both street performance and race applications.

Key Features:

• Multiple mounting configurations available — flanged bolt-on versions attach directly to the collector ring, while slip-on weld-on versions slide over the collector and weld to the exhaust pipe, covering headers with or without a collector ring
• Precision-engineered reducer geometry ensures smooth exhaust flow transitions that minimize turbulence and back-pressure for optimal performance
• Sized to match Hooker Super Competition collector specifications for accurate, purpose-fit integration across the lineup
• Durable steel construction engineered to withstand the high-heat demands of performance exhaust environments
• Sold in pairs for a complete left/right dual-exhaust installation
• Emissions compliant — legal for use on emissions-controlled, non-emissions-controlled, and racing-use-only vehicles
• Compatible with custom exhaust fabrication, complete system builds, and mixed-diameter installations

To select the correct reducer, match the inlet diameter to your header collector's outer diameter, then choose the flanged bolt-on style if your header features a collector ring, or the slip-on style if it does not. Each kit includes one pair of reducers, providing everything needed to connect both sides of a dual-exhaust setup.

Hooker's Racing Heritage

Since 1962, Hooker Headers has been a defining force in performance exhaust engineering. The Hooker philosophy has always been to make maximum horsepower and put it at the optimum point in the power curve — a commitment that has made Hooker the benchmark for exhaust development in automotive performance and drag racing. That same standard of precision engineering is carried through to every Super Competition Reducer, ensuring the connection between your headers and exhaust system is never the weak link in your performance build.
