Catco Exhaust Manifold with Integrated Catalytic Converter

Catco Exhaust Manifolds with Integrated Catalytic Converters

When an exhaust manifold and catalytic converter fail together — a common scenario on many domestic and import vehicles — replacing them as a single integrated unit is often the most efficient and reliable solution. Catco has built its reputation squarely on this kind of precision engineering, and its line of exhaust manifolds with integrated catalytic converters reflects decades of expertise in emission control technology.

A Brand Built on Emission Control Expertise

Since opening its doors in Hobart more than two decades ago, Catco has grown to be the worldwide source for technologically advanced catalytic converters for today's OBD II and Pre-OBD II systems, manufacturing advanced aftermarket and OEM emission control solutions that improve air quality. Professional technicians count on Catco for high quality, easy-to-install products, and the brand prides itself on leading the industry in new product development and efficient manufacturing processes, setting the industry standard from design and testing all the way through metal forming, welding, and final assembly.

What Sets Catco's Manifold-Converter Units Apart

The integrated design of Catco's exhaust manifold and catalytic converter units eliminates the separate pipe connections, gaskets, and hardware required when replacing each component individually. This translates to a cleaner installation and fewer potential leak points. Made by Catco with an environmentally conscious approach, these converters feature advanced ceramic substrates for reducing pollution and are expertly manufactured from superior stainless steel materials using leading-edge equipment at the company's facility, then thoroughly tested to ensure maximum dependability and long-lasting use.

Catco's integrated units feature Aristo Clean by Design® advanced catalyst technology to handle the toughest emissions problems. Key engineering highlights include specifically engineered fitment for OBD II-equipped vehicles, "Clean By Design" ceramic substrates for maximum pollution reduction, larger total substrate size, increased precious metals loading, improved O2 storage and release, and 409 stainless steel shell and neck construction for longer service life.

EPA Compliance and Warranty Coverage

Catco's exhaust manifold with integrated catalytic converter is a Federal (EPA) compliant part, legal for use on vehicles built to meet Federal EPA standards, though it is not legal for installation on vehicles required to meet CARB standards and/or registered in California and other states following CARB standards. Buyers should confirm their state's requirements before purchasing.

Catco backs its integrated manifold-converter units with a meaningful warranty. The converter is designed and manufactured to meet federal EPA emission requirements for 25,000 miles, while the stainless steel body and nipples are warranted for 5 years or 50,000 miles, whichever comes first.

The Right Choice for Direct-Fit Replacement

Catco's integrated manifold-converter parts are specifically designed to fit your vehicle with a no-hassle installation, and they have become the products of choice for many professional technicians in the automotive and light-duty trucking industries. Whether you're a DIY enthusiast or a shop professional dealing with a failed manifold-cat assembly, Catco delivers a bolt-in replacement engineered to OE dimensions with the emission performance your vehicle demands.
