Over high mileage, thermal shock degrades the internal washcoat, and oil-consumption blow-by common to aging horizontally opposed engines coats the ceramic substrate. This triggers persistent P0420 fault codes, chokes low-end torque, and causes restrictive exhaust backpressure.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis front manifold converter is engineered with high-grade tubular stainless steel piping and precision CNC-machined thick flanges that prevent thermal warping at the head ports. Internally, a dense, high-flow ceramic substrate washcoated with precious catalytic metals ensures rapid light-off times and thorough hydrocarbon conversion without restricting boxer exhaust scavenging.
