These Certified Automotive Experts 2.5-inch header collectors provide a simple connection between compatible 3-bolt exhaust headers and a custom exhaust system. Each collector features a standard 2.5-inch 3-bolt flange with a full 2.5-inch outlet, making the pair well suited for LS swaps, hot rods, muscle cars, street rods, and custom exhaust fabrication.
Unlike our O2-bung collector version, these collectors have a clean, uninterrupted tube with no oxygen sensor bung. This makes them a practical choice when the O2 sensor will be installed farther downstream in the exhaust system or when a sensor provision at the collector is not needed.
The collectors are manufactured from corrosion-resistant stainless steel and supplied as a matched pair. Two solid copper 2.5-inch collector gaskets are included. Copper provides a durable sealing surface capable of handling repeated exhaust heat cycles while conforming under flange clamping pressure.
Package includes two 2.5-inch stainless steel header collectors and two copper 3-bolt collector gaskets. Bolts and nuts are not included.
Before ordering, verify that your headers use a standard 2.5-inch 3-bolt collector flange and that a 2.5-inch outlet is appropriate for your exhaust system.
