Product Details

This collector adapter from Stainless Works is designed to help you connect different sections of your exhaust system. It features a 3-bolt flange that accepts a 3-inch outside diameter tubing and steps down to a 2-1/4-inch outside diameter outlet. This makes it useful for adapting headers or exhaust manifolds to a smaller diameter pipe or muffler section.

Built from 304 stainless steel, this adapter is well-built to resist corrosion, especially important in exhaust applications. The connections are TIG welded for a strong, durable bond that can handle the heat and vibration of daily driving. A notable feature is the integrated O2 sensor bung, welded into the tubing about 2 inches from the flange's inside edge, making it convenient to add or retain an oxygen sensor in your custom exhaust setup.

This part is made in the USA and comes with a limited lifetime warranty from Stainless Works. Please note that this part is not CARB approved and cannot be shipped to California.
