This Catted Downpipe kit replaces both restrictive factory units on the Mercedes-AMG C63 and C63S with high-flow sports catalytic converters, wrapped in full woven heat shielding.\u003c\/p\u003e\n\u003cp\u003eThe factory downpipes are the tightest part of the V8's exhaust, and the standard catalysts are the tightest part of them. These keep a working catalyst on each bank while releasing most of the flow a catless kit offers, which is what makes them the sensible choice on a car that still has to do the daily drive. The sports catalysts also keep the exhaust note cleaner and considerably less raspy.\u003c\/p\u003e\n\u003cp\u003eManufactured from T304 stainless steel with mandrel bends and precision TIG welding throughout, with the factory sensor bungs retained.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eHigh-Flow Sports Catalytic Converters\u003c\/h3\u003e\n\u003cp\u003eFar less restrictive than the factory units, retaining emissions control on both banks while releasing most of the flow a catless kit offers.\u003c\/p\u003e\u003ch3\u003eSupplied as a Matched Pair\u003c\/h3\u003e\n\u003cp\u003eThe M177 is a hot-vee V8 with both turbochargers mounted inside the vee, so it runs two downpipes - one per bank.
