Product Details

With this collector adapter from Stainless Works, you get a 3-bolt flange designed to connect to a 2-1/2 inch OD tubing, and it steps down to a 2 inch OD outlet. It also includes a pre-welded O2 sensor bung, positioned about 2 inches from the inside edge of the flange, making it convenient for adding an oxygen sensor to your exhaust system. This piece is made from 304 stainless steel, which is known for its good resistance to corrosion, and it's TIG welded for a strong, durable connection.

The 3-bolt flange design is common for certain header collectors, and the step-down to a 2-inch outlet allows for flexibility when connecting to different exhaust components. The inclusion of the O2 bung means you can easily integrate an oxygen sensor for engine management or monitoring purposes without needing to weld one yourself. This adapter is built to last and is backed by a limited lifetime warranty.
