Mercedes W205 C200 Downpipes – Catted & Decat Performance Exhaust Upgrades

Mercedes W205 C200 Downpipes – Unlock the Full Potential of Your C-Class

The Mercedes-Benz W205 C200 (2014–2021) delivers a perfect balance of efficiency, comfort, and performance. Equipped with either the 1.5L M264 EQ Boost mild-hybrid engine or the earlier 2.0L M274 turbo, the C200 offers excellent tuning potential. However, the restrictive OEM downpipes limit exhaust flow, turbo efficiency, and power gains. Upgrading to a performance Mercedes W205 C200 downpipe is one of the most effective modifications to improve throttle response, unlock hidden horsepower, and enhance your exhaust tone.

Why Upgrade to a Performance Mercedes W205 C200 Downpipe?

The factory downpipes are designed with emissions compliance and noise regulations in mind, which limits performance. Installing a performance downpipe delivers several key benefits:

• +20–45 HP on petrol turbo engines.
• +40–70 HP when combined with Stage 2 ECU tuning.
• Faster turbo spool – reduced backpressure allows quicker boost response.
• Lower exhaust gas temperatures – improves reliability during spirited driving.
• Enhanced exhaust note – catted offers refined sporty sound, decat delivers aggressive motorsport tone.

Types of Mercedes W205 C200 Downpipes

We offer multiple configurations of Mercedes W205 C200 downpipes tailored to your performance goals:

Catted Mercedes W205 C200 Downpipes

Catted downpipes feature a high-flow sports catalytic converter that balances improved exhaust flow with emissions compliance. Perfect for street-driven builds in regions with emissions testing.

Decat Mercedes W205 C200 Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing airflow and unlocking the highest performance potential. Best suited for track-focused builds, dyno tuning, and unrestricted setups.
