Stainless Works Collector Adapter 3-Bolt 3-1/2in OD Tubing 3in OD Outlet + O2 Bung

This collector adapter starts with 3-1/2 inch OD tubing and steps down to a 3 inch OD outlet, making it a solid choice when you need to connect different sized exhaust components. It's built from 304 stainless steel, which is known for resisting corrosion, and features a TIG-welded O2 sensor bung positioned about 2 inches from the inside edge of the 3-bolt flange. This means you can easily add a wideband or other sensor right into your exhaust system.

The 3-bolt flange is a common setup for many exhaust collectors, and the TIG welding ensures a strong, durable connection that can handle the heat and vibration of an exhaust system. Because it's made from 304 stainless steel, you can expect it to hold up well over time, even in harsh conditions. This adapter is proudly made in the USA and comes with a limited lifetime warranty from Stainless Works.
