What Is an aftermarket cat converter?
An aftermarket cat converter serves the same fundamental purpose as an OEM converter by converting toxic gases into less harmful emissions, using high-flow substrates and precision-engineered catalysts to optimize reaction efficiency. However, aftermarket options often provide more flexibility, performance gains, and cost savings for enthusiasts and fleet operators alike. To understand how these systems differ from diesel particulate filters, read this comparison at What’s the difference between a DPF and a CAT?.
Key Benefits of an Aftermarket Cat Converter
- Enhanced Emissions Reduction: Designed with advanced substrates, an aftermarket cat converter can reduce NOx, CO, and hydrocarbons more efficiently, helping vehicles meet stricter standards. Learn more about particulate filtration from the in-depth analysis of DPFs and catalytic converters.
- Improved Vehicle Performance: Optimized flow design minimizes backpressure, boosting horsepower and torque—as seen in our Volvo catalytic converter tests—while maintaining consistent exhaust temperatures for reliable throttle response. The role of catalyst structures is further detailed in the catalytic converter overview.
- Value for Money: At Catman, all our converters are backed by a minimum 12-month guarantee, offering durability without breaking the bank. Explore affordable catalytic converters that deliver premium performance at competitive prices.
Enhanced Emissions Reduction
Modern aftermarket cat converter technology focuses on maximizing the chemical reactions that convert pollutants into water vapor, nitrogen, and carbon dioxide, leading to cleaner exhaust output and compliance with the latest emission regulations. Reactive surfaces are coated to withstand high temperatures and corrosive environments, ensuring long-term efficiency. Discover comprehensive details in this DPF, SCR, and AdBlue integration guide.
Boosted Performance
By utilizing high-grade stainless steel casings and precision-engineered monoliths, our aftermarket cat converter designs ensure laminar flow, reducing exhaust restriction and improving throttle response. Consistent backpressure management also supports efficient turbocharger operation, enhancing mid-range torque.

Installation Guide for Your Aftermarket Cat Converter
- Prepare the Vehicle: Ensure the engine is cool, lift the vehicle safely, and use protective equipment to prevent burns and injury.
- Remove the Old Converter: Apply penetrating oil to fasteners and follow manufacturer removal procedures to avoid damaging flanges or sensors.
- Fit the New Converter: Align the flange, use new gaskets, and tighten bolts to specified torque values to ensure a proper seal.
- Inspect for Leaks: Start the engine, let it idle, and check all connections for exhaust leakage. Refer to these essential mounting considerations.
Maintenance Tips
Regularly inspect your aftermarket cat converter for damage, clean oxygen sensors, and avoid unburned fuel entering the system to prolong its lifespan. Preventive measures like scheduled regens and use of high-quality fuels can reduce the risk of clogging. For insights on diesel filter care, see DPF vs. catalytic converter differences.
