TRANS-DAPT 9374 3-Inch to 2.5-Inch Collector Header Reducers, 3-Bolt Flange, Aluminized Steel, Pair

The TRANS-DAPT 9374 Collector Reducer Pair provides a practical connection between headers or collectors with a 3-inch inlet and exhaust tubing with a 2.5-inch outlet. Designed for exhaust system installation and replacement applications, these reducers help simplify transitions between different pipe sizes while supporting a secure, properly aligned connection.
Constructed from aluminized steel, the TRANS-DAPT 9374 reducers offer durability and corrosion resistance for demanding automotive exhaust environments. Each reducer uses a 3-bolt flange design to help provide a stable connection when matched with compatible header and exhaust components. The pair format makes this set convenient for applications requiring reducers on both sides of a dual exhaust system.
These 3-inch header reducers are intended for use with compatible exhaust components and mounting hardware. Verify the flange pattern, pipe sizes, clearance, and vehicle-specific requirements before installation. The TRANS-DAPT 9374 is a dependable choice for exhaust fabrication, header upgrades, and replacement projects where a 3-inch collector outlet must transition to 2.5-inch tubing.
