This catted performance downpipe replaces the restrictive factory unit on the Mercedes-AMG GLE53, GT43, GT50 and GT53 with a high-flow sports catalytic converter and full woven heat shielding.\u003c\/p\u003e\n\u003cp\u003eThe factory downpipe is the single biggest restriction in the system, and the standard catalyst is the tightest part of it. This one keeps a working catalyst in the system while releasing most of the flow a catless pipe offers, which is what makes it the sensible choice on a car that still has to do the daily drive. The sports catalyst also keeps the exhaust note cleaner and considerably less raspy.\u003c\/p\u003e\n\u003cp\u003eManufactured from 304 stainless steel with mandrel bends and precision TIG welding throughout, wrapped in woven heat shielding, with the factory sensor bungs retained in their original positions.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eHigh-Flow Sports Catalytic Converter\u003c\/h3\u003e\n\u003cp\u003eA far less restrictive catalyst than the factory unit, retaining emissions control while releasing most of the flow a catless pipe offers.\u003c\/p\u003e\u003ch3\u003eBuilt for the Electrified M256\u003c\/h3\u003e\n\u003cp\u003eThe M256 pairs a conventional turbocharger with an electric auxiliary compressor and a 48-volt starter-generator, so it builds boost almost instantly. That responsiveness is exactly why the restriction downstream is so noticeable - the engine makes the pressure quickly and then has to push it through a factory downpipe built to a noise target.\u003c\/p\u003e\u003ch3\u003eFull Woven Heat Shielding\u003c\/h3\u003e\n\u003cp\u003eWrapped over the length of the pipe, reducing radiant heat into the engine bay and protecting the components packed around it.\u003c\/p\u003e\n\u003ch3\u003e304 Stainless Steel Construction\u003c\/h3\u003e\n\u003cp\u003eHigh-grade, corrosion-resistant material built to withstand the exhaust gas temperatures a tuned M256 produces.\u003c\/p\u003e\n\u003ch3\u003eFactory Sensor Bungs Retained\u003c\/h3\u003e\n\u003cp\u003eThe oxygen sensors plug straight back into their original positions.\u003c\/p\u003e\n\u003ch3\u003eCleaner Tone Than Catless\u003c\/h3\u003e\n\u003cp\u003eThe catalyst takes the hard rasp out of the note, which is the difference between a car you still enjoy on a long drive and one you do not.\u003c\/p\u003e\n\u003ch3\u003eDirect Bolt-On Fitment\u003c\/h3\u003e\n\u003cp\u003eMounts to the factory turbo flange and mid section using the original mounting points and brackets, with no cutting or fabrication.\u003c\/p\u003e\n\u003ch2\u003ePerformance Benefits\u003c\/h2\u003e\n\u003cp\u003e Strong gains in power and torque across the rev range when tuned\u003cbr\u003e Faster spool on an engine that already responds instantly\u003cbr\u003e Sharper throttle response\u003cbr\u003e A deeper inline-six note without the rasp and drone of a catless pipe\u003cbr\u003e Far less likely to trigger a check engine light than a catless downpipe\u003cbr\u003e Lower under-bonnet temperatures thanks to the shielding\u003c\/p\u003e\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\n\u003cp\u003eMercedes-AMG GLE53 (W167, 2019-2023)\u003cbr\u003eMercedes-AMG GT53 4-Door Coupe (X290, 2019-2023)\u003cbr\u003eMercedes-AMG GT50 4-Door Coupe (X290, 2019-2023)\u003cbr\u003eMercedes-AMG GT43 4-Door Coupe (X290, 2019-2023)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.0L Turbocharged M256 Inline-Six with EQ Boost\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll four cars share the same M256 engine and downpipe layout, which is why one part covers the range.
