Mercedes-Benz W205 C450 Catless Downpipes — M276 3.0L BiTurbo V6
YPG Motorsport catless downpipes for the Mercedes-Benz C450 AMG Sport (W205) replace the restrictive factory catalytic converters on the M276 3.0L BiTurbo V6 with mandrel-bent stainless steel pipes. The C450 is the predecessor to the C43 — sharing the same M276 engine architecture and responding to the same tuning modifications.
Removing the factory cats delivers faster turbo spool, sharper throttle response, and a noticeably sportier exhaust note. When paired with a Stage 2 ECU calibration, the C450 delivers 420–450 HP and 420–450 lb-ft of torque — a serious jump from the factory 362 HP.
