Unburned hydrocarbons and thermal fatigue cause the internal matrix to foul, melt, or fracture internally. This leads to restricted exhaust gas velocity, loss of top-end torque, unburnt fuel odors, and downstream oxygen sensor mismatch triggering persistent \u003cstrong\u003eP0420\u003c\/strong\u003e and \u003cstrong\u003eP0430\u003c\/strong\u003e diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to supersede OEM reference \u003cstrong\u003e30531\u003c\/strong\u003e, this converter utilizes a heavy-gauge stainless steel outer shell designed to withstand high exhaust gas temperatures and external road salt corrosion.
