Bull-X 2.75″ downpipe, Mercedes C 200–350 W205

A downpipe is one of the most popular upgrades for a turbocharged engine. Efficient exhaust flow is important for a turbo system, and a freer-flowing pipe can provide a sportier sound while improving throttle response and power potential.

This product does not have model-specific ECE approval. It is intended for motorsport and other off-road enthusiast use. Always check the current road regulations before installation.

Bull-X 2.75″ downpipe, Mercedes C 200–350 W205 is a vehicle-specific stainless-steel assembly for Mercedes-Benz C-Class W205/S205/C205 models with the M274 engine. Its 70 mm / 2,75″ pipe size and freer-flowing design reduce exhaust back pressure and allow the turbocharger to operate with less restriction, particularly on tuned engines.

Lower back pressure can improve turbo response and throttle response while reducing thermal load on the exhaust side. The vehicle-specific design replaces the original component without unnecessary fabrication.

• Pipe diameter 70 mm / 2,75″
• Manufactured from stainless steel
• Vehicle-specific plug-and-play design
• Freer-flowing construction reduces exhaust back pressure
• Helps reduce thermal load on the turbo and exhaust side
• Optional integral heat shielding is available
• Connects to the original exhaust system
• Made in Germany
• Key fitment detail: M274.920 engine

Catalytic-converter options

• With a 100-cell sports catalytic converter
• With an HJS 200-cell sports catalytic converter without model-specific ECE approval
• With a 200-cell sports catalytic converter
• With a Bull-X EOBD 200-cell sports catalytic converter
• With a catalytic-converter replacement pipe

The available catalytic-converter configurations do not include model-specific ECE approval. Do not use an unapproved product on public roads; always check the current road regulations.

Unapproved catalytic-converter options or a catalyst-delete version may trigger a fault code related to the downstream oxygen sensor. Any required software changes depend on the vehicle ECU and selected version.

The HJS 200-cell option carries an approval mark, but it is not assigned to Mercedes W205 applications. It therefore does not provide vehicle-specific road approval for this product.

Examples of compatible vehicles

• Mercedes-Benz C 200 W205/S205/C205 (2013–)
• Mercedes-Benz C 200 4Matic (2015–)
• Mercedes-Benz C 250 (2014–)
• Mercedes-Benz C 300 (2015–)
• Mercedes-Benz C 350 e (2015–)

Before ordering, verify the vehicle engine and body version, engine code and the exact vehicle coverage of the selected catalytic-converter approval.
