Catco: The Professional's Choice for Emissions & Exhaust
When professional technicians need emissions parts they can trust, they turn to Catco — one of the most recognized names in the automotive aftermarket for catalytic converters and exhaust emission control products. Catco operates under the umbrella of AP Emissions Technologies, a Goldsboro, North Carolina-based manufacturer with roots stretching back to 1927. Catco catalytic converters have earned a reputation as "the professional's choice" thanks to a relentless focus on quality manufacturing, precise OE fitment, and full regulatory compliance.
A Legacy Built on Emissions Expertise
The Catco brand was launched in 1990 by the Proimos family, who founded Aristo as a niche manufacturer of catalytic converter catalysts before expanding into full converter production. In 2011, Catco was acquired by AP Exhaust — a move that combined decades of exhaust manufacturing know-how with Catco's specialized emissions chemistry. Today, Catco benefits from AP Emissions' vertically integrated manufacturing operation, where everything from catalyst formulation to metal forming, welding, and final assembly happens under one roof. This end-to-end control means every part is built to exact OE dimensions and performance standards.
Aristo Clean by Design®: Advanced Catalyst Technology
At the heart of Catco's product line is the proprietary Aristo Clean by Design® advanced catalyst technology. This system uses premium-grade ceramic substrates with increased precious metal loadings to improve oxygen storage and release, lower emissions output, and keep the MIL (check engine) light off over the long haul. Catco's catalytic converters are specifically engineered for both OBDII and pre-OBDII vehicles and are available in direct-fit and universal configurations to serve a wide range of domestic and import applications.
Full Compliance with EPA and CARB Standards
Emissions regulations vary significantly by state and locality, and Catco takes compliance seriously. The brand's converters carry both Federal (EPA) and California (CARB) approvals, making them suitable for use in even the strictest emissions-testing markets. This includes exhaust manifold converters with integrated catalytic converters — direct-fit manifold and warm-up cats that are among the hardest-to-find applications in the aftermarket. These integrated units are engineered to match OE sensor locations and mounting geometry, simplifying installation and reducing comebacks.
Coverage for Diesel Applications
Beyond gasoline-powered vehicles, Catco's parent AP Emissions has expanded its emissions portfolio into the diesel segment. Diesel oxidation catalysts (DOCs) play a critical role in reducing harmful exhaust emissions from diesel engines by converting carbon monoxide and hydrocarbons into carbon dioxide and water. As part of the broader AP Emissions family — which includes the DuraFit brand of diesel emission products — Catco-branded DOC solutions bring the same engineering rigor and compliance standards to commercial and light-duty diesel applications.
