What material is this collector adapter made from?

This collector adapter is made from 304 stainless steel, chosen for its strength and resistance to corrosion, which is ideal for exhaust components.

What is the purpose of the O2 bung?

The O2 bung is a pre-welded port designed to accept an oxygen sensor. This is useful for custom exhaust systems where you need to install an aftermarket or relocated O2 sensor.

What does TIG welded mean for this part?

TIG welding is a high-quality welding process that creates strong, precise, and clean welds. For this collector adapter, it means the joints are built to last and withstand the stresses of an exhaust system.

Product Details

If you're fabricating or modifying an exhaust system, you'll need a solid way to connect different pipe sizes or collector styles. This collector adapter from Stainless Works is built to handle the job. It's designed to join a 3-bolt flange to a 3-1/2 inch OD exhaust tube, and it includes a handy O2 sensor bung already welded in place, saving you a step during installation.

This adapter is made from 304 stainless steel, which is a strong material that resists corrosion well, especially important for exhaust components that deal with heat and moisture. The welds are TIG welded, a process known for creating strong, clean joints that hold up over time. The flange uses a 3-bolt pattern, and the outlet is also 3-1/2 inches in OD. The O2 bung is positioned about 2 inches from the inside edge of the flange, giving you a good spot to install your sensor.

This part is a universal fit, meaning it's intended for custom exhaust builds where precise fitment is achieved through fabrication. It comes with a limited lifetime warranty from Stainless Works.
