Spools like a different car
Backpressure gone. Boost comes in a full 400rpm sooner and it pulls all the way to redline now. Fitment was dead-on — no massaging, no fighting the O2 bungs.

The details
The MBH Motorsports W205 C63 AMG Biturbo Downpipes are the ultimate performance upgrade for your M177-powered Mercedes. The factory exhaust system heavily restricts the 4.0L biturbo V8, choking its true capabilities. By eliminating these severe bottlenecks, our downpipes maximize exhaust gas flow, allowing your engine to breathe and operate at peak efficiency. This optimized scavenging allows the turbos to spool faster, resulting in highly noticeable and aggressive horsepower and torque gains.
When you invest in a premium vehicle like the W205 C63 or C63S, risking your engine with cheap, mass-produced imported components is not worth it. Don't fall for the fancy marketing of overseas imports; at MBH Motorsports, we don't make parts for everyone. We focus exclusively on crafting the absolute best exhaust systems specifically for Mercedes-Benz. Fabricated from heavy-duty 16-gauge 304 American stainless steel and meticulously precision TIG welded right here in the United States, we guarantee there is no better-built downpipe on the market for your AMG.
