Over time, continuous thermal cycling leads to internal ceramic monolith crumbling, washcoat deterioration, and sintering of precious metal catalyst coatings. This degradation restricts exhaust scavenging, increases cylinder head backpressure, dulls throttle response, and triggers persistent P0420 and P0430 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed with durable stainless steel outer shells and high-efficiency ceramic substrates, this replacement converter pair restores exhaust velocity and emissions compliance for EPA-registered jurisdictions.
