It replaces the restrictive factory downpipe section with larger 2.5-inch mandrel-bent tubing and a 200-cell metallic high-flow catalyst.\u003c\/p\u003e\n\n\u003cp\u003ePLM uses 18-gauge 304 stainless steel, a thick CNC-machined manifold flange, and hand TIG welds for a durable, factory-location fit. The downpipe bolts directly to the factory exhaust and includes the gaskets and hardware needed to install it.\u003c\/p\u003e\n\n\u003cp\u003eThe high-flow catalyst is designed to reduce exhaust restriction while keeping a catalytic converter in the system. For Prelude owners building out the exhaust, it is a clean starting point that is made specifically for the BF1 platform rather than adapted from another Honda application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eWhat to Know Before Installing a Prelude Downpipe\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003ePLM recommends adding a 90-degree secondary O2 sensor adapter to help prevent a check-engine light. An adapter can improve sensor placement, but it does not guarantee that a warning light will not appear.\u003c\/p\u003e\n\n\u003cp\u003eThis is a direct-bolt-on exhaust part, but it still changes an emissions-related component. Confirm emissions legality where you drive before installation, and make sure the exhaust is fully sealed and the O2 sensor wiring is routed clear of heat and moving parts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eAbout PLM\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003ePrivate Label Mfg., better known as PLM, has been developing value-focused performance parts for enthusiasts since 2005.
