About this part

Product Details

Built from 304 stainless steel, this collector adapter is made to resist corrosion, even in harsh exhaust environments. It features a 3-bolt flange designed to connect to a 2-1/2 inch OD tubing setup, transitioning to a 2-1/4 inch OD outlet. This makes it a solid choice for custom exhaust work where you need to adapt different pipe sizes.

The adapter is TIG welded for a strong, durable connection that holds up over time. It also includes a pre-welded O2 sensor bung, conveniently placed about 2 inches from the inside edge of the flange. This placement is common for exhaust setups that need to accommodate an oxygen sensor without requiring additional welding during installation.

This part is proudly made in the USA and comes with a limited lifetime warranty, reflecting the well-built nature of the product.
