Description

Catalytic converters are specifically designed to keep pollutants out of the air, but replacing a failing converter isn't only for the environmentally-conscious; it will also help restore lost horsepower to your ride. Magnaflow semi-universal catalytic converters are a great way to bring your vehicle up to code, and maybe find some of that missing performance.

Magnaflow catalytic converters are designed to scrub exhaust for harmful elements, while also being as non-restrictive to exhaust flow as possible. Magnaflow uses a ceramic catalyst that is ideal for allowing airflow. A ribbed body design coupled with overlapped welds help to ensure a durable catalytic converter.

Magnaflow offers a massive selection of semi-universal catalytic converters. All Magnaflow catalytic converters are 49 state legal to meet or exceed your states emissions laws, and there is also a full line of 50 state legal catalytic converters that are California CARB approved.

So, if your catalytic converter is rattling, and something smells like rotten eggs, you're in luck. Magnaflow semi-universal catalytic converters are the solution you've been looking for. Get yours today, and get your ride back on the road.

Order Notes

Please Note: If you live in California, you must order a California approved converter to meet Carb emissions requirements. We are not authorized to ship 49 State converters to a California address.

Vehicles in New York State with CARB certification will require 49 state, OEM grade catalytic converters. Vehicles in New York State with EPA certification will require 49 state, non-OEM grade catalytic converters. Emissions tag is often found under the hood, on the strut tower, or the front core support.
