2.5-Inch Stainless Steel Exhaust Header Collectors with O2 Sensor Bungs
Connect your headers to a custom exhaust system with these 2.5-inch Stainless Steel Exhaust Header Collectors, designed for compatible headers with a 2.5-inch, 3-bolt collector flange. Each collector features a full 2.5-inch inlet and outlet, stainless steel construction, and an integrated oxygen sensor bung with a threaded plug.
The collectors offer three selectable clocking positions, allowing you to adjust their orientation to help position the O2 sensor around nearby chassis, steering, transmission, engine, and exhaust components. Compatible with narrowband and wideband oxygen sensors, they are suitable for custom exhaust fabrication, LS swaps, muscle cars, hot rods, street rods, and race car applications using the appropriate collector flange.
