Product Details

This is a collector adapter from Stainless Works, designed to help you connect different exhaust components. It features a 3-bolt flange that accepts 3-1/2 inch OD tubing and steps down to a 2-1/2 inch OD outlet. This part is useful when you need to adapt a header collector or other exhaust piece to a different size pipe or muffler inlet.

It's constructed from 304 stainless steel, which is known for resisting corrosion, and the seams are TIG welded for a strong, durable connection. A handy O2 sensor bung is already welded into the tubing, positioned about 2 inches from the inside edge of the flange, making it convenient for adding an oxygen sensor to your exhaust system. This adapter is a well-built piece that should hold up well over time.
