The details
Specs & details
The Mercedes S63 AMG is the undisputed king of luxury performance, delivering an unmatched blend of executive refinement and twin-turbo V8 muscle. MBH Motorsports S63 Biturbo Downpipes are engineered to push that platform into true supercar territory. By eliminating the extreme flow restrictions of the factory exhaust manifolds, these downpipes sharply reduce backpressure and accelerate turbo spool, elevating your S63 Biturbo to Lamborghini-rivaling levels of acceleration.
When paired with performance ECU software, this system delivers massive gains of over 100 wheel horsepower and 200 ft-lbs of wheel torque, placing your S63 AMG in a class all its own.

Every set of MBH downpipes is proudly hand-fabricated in the USA from heavy-duty, 16-gauge T-304 American stainless steel to ensure lifetime resistance against cracking, warping, and extreme exhaust temperatures.
