Engineered for petrol models without a particulate filter, this performance catalyst delivers the flow your 2.0T wants while retaining emissions control. We have installed this unit on customer cars and the feedback has been outstanding – quicker spool, sharper throttle and a smoother pull to the redline with no warning lights on non GPF vehicles.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWhat you will feel\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eFaster boost build and crisper throttle pick-up\u003c\/li\u003e\n    \u003cli\u003eStronger torque in real-world driving\u003c\/li\u003e\n    \u003cli\u003eSmoother top-end power that keeps pulling\u003c\/li\u003e\n    \u003cli\u003eNo CEL on cars without a particulate filter\u003c\/li\u003e\n    \u003cli\u003eEuro 6 compliant and MOT friendly as per manufacturer guidance\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eWhy the Eddy Catalytic design works\u003c\/h3\u003e\n  \u003cp\u003e\n    Stone’s patented eddy catalyst shapes exhaust gas into a controlled vortex. At lower engine speeds it increases purification efficiency and maintains the pressure your turbo needs to light up quickly. As revs climb the flow path opens, giving top-end performance comparable to a 100-cell sports catalyst while keeping low-speed cleaning performance closer to a 400-cell unit. O2 sensor placement is optimised for accurate feedback and smooth delivery.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eProven gains\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003ePower increase: +7.1 PS at 5,988 rpm\u003c\/li\u003e\n    \u003cli\u003eTorque increase: +20.60 Nm at 4,461 rpm\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eBuilt for performance and longevity\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eSUS304 stainless steel tubing for durability and heat resistance\u003c\/li\u003e\n    \u003cli\u003e7-axis CNC mandrel bending for up to 98 percent roundness and precise flow\u003c\/li\u003e\n    \u003cli\u003eCFD-style development and 3D-scanned OEM geometry for perfect routing\u003c\/li\u003e\n    \u003cli\u003eCrisscross and overlapping welds at the turbo flange for strength under extreme heat\u003c\/li\u003e\n    \u003cli\u003eRobotic spot welding for consistency and penetration\u003c\/li\u003e\n    \u003cli\u003eDirect bolt-on with OEM-style connections – no cutting required\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cp\u003eFor BMW 2.0 turbo petrol B48 engines without a gasoline particulate filter:\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eG20 3 Series – 320i, 330i\u003c\/li\u003e\n    \u003cli\u003eG30 G31 5 Series – 520i, 530i\u003c\/li\u003e\n    \u003cli\u003eG02 X4 – 20i, 30i\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cp\u003eReplaces the factory primary catalyst section on applicable non GPF models.\u003c\/p\u003e\n\n  \u003ch3\u003ePart number\u003c\/h3\u003e\n  \u003cp\u003eStone Exhaust Part No. A216E\u003c\/p\u003e\n\n  \u003ch3\u003eReal customer results\u003c\/h3\u003e\n  \u003cp\u003e\n    We have fitted this performance catalyst on multiple B48 cars in-house.
