For safety and legal reasons, a faulty catalytic converter can’t be ignored. The catalytic converter does the job of transforming toxic gases into less harmful compounds and a malfunctioning converter could cause poor vehicle performance and/or a failed emissions test. If you need a direct fit catalytic converter, Walker has a wide range of direct replacements for OE converters that will require no modifications to install. Walker's parts fit like OE because Walker is the catalytic converter supplier to many vehicle manufacturers. Catalytic converters by Walker are designed with an ample precious metal loading to ensure the required reduction of emissions is achieved. They are constructed and manufactured to satisfy all EPA policy and emission control requirements.

The Exhaust Manifold with Integrated Catalytic Converter has thick OE-style flanges for greater strength and OE-style routing for straightforward installation. Hangers and sensor fittings are included if required by application. It features leading-edge washcoat technology to ensure premium performance. The catalytic converters that are not CARB (California Air Resource Board) compliant are backed by 25,000 miles catalytic performance and 5 years/50,000 miles structural integrity warranty. The catalytic converters that meet CARB regulations and are legal in California are covered by 5 years/50,000 miles catalytic performance and structural integrity warranty.

Walker is the world's leading manufacturer of automotive exhaust systems and emission control products for the replacement and OE markets. It offers complete engine-to-tailpipe exhaust solutions and exploits modern emission control technologies that fully satisfy the needs of the automotive industry. Walker has introduced a long line of innovations that revolutionized the market and set new standards for quality and durability.

Good Quality
The catalytic converter looks just like the description. I brought it to the local muffler shop and they said it was a good brand to go with. They had no issues installing it. It wasn't the most expensive or the cheapest either. But it got the job done. Should last the rest of the life of the car. If it doesn't, I'll get back on here and make a complaint about it.

Perfect Fit !
As any old timer knows, when a piece of your exhaust system rusts out, replace the whole system all at the same time. Well I forgot to take my own advice and ended up replacing the whole system a piece at a time. I was nervous ordering so many parts online, but from what I could find out CARiD seemed to have a good reputation. Well, everything fit perfectly! The only problem was getting all the rusty old crap out. The new parts went in like a charm. This was for a 12 year old foreign car.
