It delivers sharper turbo response, stronger exhaust flow, and a deeper, more aggressive exhaust note.\u003c\/p\u003e\n\u003cp\u003eThe 304 stainless-steel construction is paired with an integrated thermal insulation layer to help reduce radiant heat transfer to nearby components. A stainless flex section accommodates engine movement and thermal expansion, while the factory-style oxygen-sensor provisions support direct installation. The catalyst and sensor layout are engineered for CEL-free operation on supported vehicles without requiring ECU calibration.\u003c\/p\u003e\n\u003ch3\u003eCommon B58 Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2020+ Toyota GR Supra A90 \/ A91 3.0 - B58 engine\u003c\/li\u003e\n\u003cli\u003e2020+ BMW G20 \/ G21 M340i 3.0\u003c\/li\u003e\n\u003cli\u003e2018+ BMW G30 \/ G31 540i 3.0\u003c\/li\u003e\n\u003cli\u003e2018+ BMW G32 640i 3.0\u003c\/li\u003e\n\u003cli\u003e2019+ BMW G14 \/ G15 \/ G16 840i 3.0\u003c\/li\u003e\n\u003cli\u003e2019+ BMW G29 Z4 M40i 3.0\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSuper 150-cell high-flow catalytic converter\u003c\/li\u003e\n\u003cli\u003eIntegrated thermal insulation layer to reduce radiant heat\u003c\/li\u003e\n\u003cli\u003e304 stainless-steel construction\u003c\/li\u003e\n\u003cli\u003eDesigned for CEL-free operation with no ECU calibration required on supported vehicles\u003c\/li\u003e\n\u003cli\u003eIntegrated flex section and oxygen-sensor provisions\u003c\/li\u003e\n\u003cli\u003eImproved exhaust flow, turbo response, and a deeper exhaust note\u003c\/li\u003e\n\u003cli\u003e6-month limited product warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntended for street and performance use where permitted; a 150-cell sport catalyst does not guarantee emissions inspection approval in every jurisdiction.\u003c\/li\u003e\n\u003cli\u003eCEL performance can vary with vehicle software, sensor condition, fuel quality, and regional emissions specification.\u003c\/li\u003e\n\u003cli\u003eConfirm the VIN and original downpipe configuration before ordering.
