Premium Catalytic Converter Upgrade by aFe Power

Upgrading or replacing your catalytic converter isn’t just about emissions compliance–it's also a chance to improve performance and efficiency. The aFe Direct Fit Catalytic Converter Replacement for the 2009-2023 Ram 1500 5.7L HEMI is a high-quality, direct-fit solution designed to replace a failing or restrictive factory catalytic converter. Built from mandrel-bent 409 stainless steel, this system ensures smooth, unrestricted exhaust flow. Unlike stock units that can be prone to bottlenecking and degradation over time, this setup utilizes precision-engineered 2.5" to 3" tubing to maintain proper backpressure even when your applications become extreme. The mitered merge collector is another key upgrade, helping to streamline exhaust gases and improve velocity for quicker throttle response and more efficient combustion. The result is a system that not only helps restore lost power but also enhances overall engine performance.

EPA Complaint System

This EPA-compliant catalytic converter is designed to bolt right up using factory mounting locations, making installation hassle-free. There's no cutting or welding required, and the system retains the factory O2 sensor locations for seamless integration with your truck’s ECU. Each unit is also 100% MIG-welded for long-term durability, ensuring it can withstand harsh conditions, extreme temperatures, and off-road abuse with ease. The precision-cut heavy-duty flanges provide a leak-free seal, so you won’t have to worry about annoying exhaust leaks or poor fitment.
