The w204 chassis C-Class comes with many engines and badge numbers. The good news is these MBH Motorsports W204 C-Class headers will fit and W204 chassis C-class that has the M272 engine. Such as C300 and C350. These headers will free up the exhaust flow and gain you about 30 horsepower over stock. As always our headers are made here in the USA (Arizona) and are made from 16 gauge 304 stainless steel. The same quality we put into our other headers we put into these.
