Construction & Design

This catalytic converter is expertly crafted from high-strength 16 gauge 409 stainless steel tubing, known for its excellent corrosion resistance and long service life. The spun body design faithfully replicates the original equipment’s flow dynamics, ensuring that factory-level performance and fuel efficiency are preserved.

A single laser fusion weld enhances the structural integrity of the converter and reduces the risk of exhaust leaks. The compact, low-mass construction promotes better thermal management, which supports consistent catalytic activity and emissions control. Mandrel-bent tubing maintains a smooth exhaust flow path, preventing restrictions that could negatively impact engine output or fuel economy.

Additionally, the corrosion-resistant 410 stainless steel barbed hangers help isolate vibrations and reduce noise, contributing to a quieter and more comfortable ride.
