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
Specs & details
The CL63 AMG reigns supreme as the king of luxury-performance coupes, combining absolute refinement with blistering power. At MBH Motorsports, our goal was to elevate the CL63 AMG Biturbo beyond its luxury roots and push it to supercar-killing, Lamborghini levels of performance. By replacing the highly restrictive factory exhaust components with our high-flowing downpipes, we unlock the massive potential hidden within the biturbo engine.
When paired with proper ECU tuning, these downpipes allow the turbos to spool faster and breathe freely, delivering jaw-dropping gains of over 100 wheel horsepower and 170 wheel torque. This staggering increase in output ensures your CL63 AMG Biturbo will sit in a class all its own, dominating the track.
Handcrafted USA Quality & Precision Fitment
Proudly handcrafted right here in the USA, our CL63 Biturbo downpipes are fabricated from heavy-duty 16-gauge T-304 American stainless steel. Built to endure the extreme heat and pressure of the biturbo V8, they offer unmatched thermal endurance and durability. Furthermore, this system is precision-engineered to perfectly accommodate both All-Wheel Drive (4MATIC) and Rear-Wheel Drive (RWD) drivetrains.
