High-Flow Honda Sport Catalytic Converter

This is an aftermarket high-flow 'sport' catalytic converter designed for Honda performance applications. Physically, the item features a cylindrical stainless steel body with a modular construction consisting of multiple welded segments and tapered end-caps to optimize exhaust flow. The exterior displays significant heat-induced discoloration, ranging from straw-gold to deep violet and magenta iridescent hues, which is typical for performance exhaust components that have been subjected to high operating temperatures. It includes a pre-drilled and welded bung for an oxygen (O2) sensor protruding from the side. The inlet and outlet flanging suggests a direct-fit or bolt-on design for specific Honda exhaust manifolds or downpipes. There is visible surface oxidation and 'bluing' of the metal, and the welds appear to be robotic or TIG-style, indicating a high-quality manufacturing process focused on durability. Minor surface scratches and carbon buildup are present near the pipe ends. The presence of a high-flow substrate internally is implied by the 'sport' designation, allowing for improved horsepower compared to restrictive factory OEM units while still providing essential emissions scrubbing via precious metals like platinum, palladium, or rhodium coated on a ceramic or metallic honeycomb core. The overall condition is used but structurally sound, with no visible cracks or punctures in the casing.
