Catless Design for Maximum Exhaust Flow
By removing the restrictive factory catalytic converter, this downpipe dramatically increases exhaust velocity and reduces backpressure. The result? A significant bump in horsepower and torque, especially when paired with tuning. Ideal for enthusiast builds that demand maximum output.
Sharper Turbo Response and More Power
The turbo spools faster with less restriction, delivering a more immediate throttle feel, stronger mid-range power, and better top-end pull. This makes your M256-powered Mercedes feel more alive, responsive, and ready to perform in any driving situation.
Aggressive, Motorsport-Inspired Exhaust Note
Going catless transforms the character of your vehicle. Expect a deeper, throatier exhaust tone with pronounced turbo sounds, sharper crackles, and an overall more visceral soundtrack. Whether you’re carving through back roads or lighting up the track, this downpipe gives your Mercedes the voice it deserves.
Premium 304 Stainless Steel Construction

Direct Bolt-On Fitment
