Mercedes CLS550/E550 Catless Downpipes | WSTN Performance (M278 W218/W212)

Mercedes-Benz CLS550 / E550 Downpipes (W218/W212) M278 4.7TT | WSTN Performance The M278 is one of the finest twin-turbo V8s Mercedes-Benz has ever produced smooth, torque-rich, and capable of far more than the factory configuration allows. These WSTN Performance downpipes remove the restrictive catalytic converters and unlock the full character of the 4.7-litre engine: a deeper, more authoritative exhaust note, stronger mid-range pull, and measurable performance gains from a direct bolt-on fitment. Built from 304 Stainless Steel premium stainless steel with precision TIG-welded construction, these downpipes are engineered to match OEM dimensions exactly no cutting, no adapters, no compromises. Every set is personally quality checked before dispatch. If you know what the M278 is capable of, you already know what these will do.
