How does the 4-inch midpipe eliminate S58 rasp?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe factory BMW G8X twin exhaust setup produces uneven acoustic pulses, resulting in a tinny rasp above 3,500 RPM. Merging the dual pipes into a 4-inch single body blends the exhaust streams, producing a fuller, cleaner, and rasp-free sound.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e3. Will this midpipe trigger a Check Engine Light (CEL)?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The midpipe connects downstream of the primary catalytic converters and secondary oxygen sensors, ensuring factory emissions monitoring is completely undisturbed without triggering a CEL.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e4. Does installation require cutting?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes. Like all G8X midpipes connecting to the factory axle-back muffler, a clean cut at the factory dimple marks is required. Heavy-duty joiner clamps are included, making the system 100% reversible back to stock.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e5.
