Catalytic Converters - High Flow, Direct Fit



We have teamed up with Magnaflow Performance Exhaust to provide direct fit, high flow replacement catalytic converters for your Northstar car. These direct-fit converters have a 4 bolt laser cut flange fully welded to the 3 inch inlet. These have a 3 inch outlet as well that you can adapt to your existing pipe via reducers or adapters as necessary.

These are currently priced at $150-170 USD (choose your option), shipping and taxes included to Canada or the USA.

Foot note: These will work with many other GM vehicles including the 3800 powered Pontiacs, Buicks, Oldsmobiles, and Chevrolet cars with the same 4 bolt rectangular flange.



Select outlet pipe size


Sorry, we cannot ship this product to California but every other US state and Candian province it is legal for use and emissions compliant.
