Unlock hidden performance in your Mercedes-Benz W204 with the Untd. Performance Catless Downpipe, engineered specifically for the 1.8L turbocharged inline-4 engine found in the C180, C200, and C250 models (2007–2014). Designed for enthusiasts seeking maximum flow, power, and sound, this catless downpipe eliminates the factory catalytic converter—resulting in quicker turbo spool, increased horsepower, and a more aggressive exhaust note.
