Over time, thermal fatigue causes micro-cracking at the runner-to-collector weld joints, leading to persistent exhaust leaks. Internally, oil vapor contamination and heat soak degrade the factory precious metal washcoat, causing catalytic cell degradation, severe exhaust backpressure, choked high-RPM performance, and recurring P0420 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eBuilt to overcome factory fatigue issues, this direct replacement assembly features a heavy-gauge stainless steel shell and precision-cut flanges that resist warpage under extreme exhaust gas temperatures. A high-efficiency ceramic honeycomb monolith provides substantial surface area for balanced oxidation and reduction reactions, restoring proper emissions chemistry without choking exhaust flow.
