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.

Unleash Triple-Digit Power Gains
The factory downpipes on the E 63 AMG BiTurbo are highly restrictive, choking your turbos and trapping heat. By upgrading to MBH 3-inch downpipes, you drastically reduce backpressure. When combined with an ECU tune, this freer-flowing design unlocks an incredible 100+ whp and 170+ wtq, completely transforming your driving experience with relentless acceleration and a deep, aggressive exhaust note.
Bulletproof USA-Made Craftsmanship
We don't cut corners. While other shops outsource to cheap overseas manufacturers, MBH Motorsports builds these downpipes in the USA using heavy-duty 16-gauge stainless steel. Featuring robust 3-inch mandrel-bent tubing, these downpipes are built to endure the extreme heat and stress of high-horsepower applications. They are quite simply built to last a lifetime.
Perfect Fitment for AWD & RWD Models
Whether you drive a rear-wheel-drive model or a power-to-all-wheels 4MATIC variant, we have you covered. MBH downpipes are precision-engineered to clear the tighter clearances of the AWD system while maintaining an optimal flow path on RWD cars.
