The details
The Mercedes S63 Coupe is king when it comes to a luxury-based performance car. Having absolute refinement paired with aggressive twin-turbo V8 power makes for an amazing combination. Here at MBH Motorsports, we set out to take the S63 AMG Coupe to the next level of performance. Fitted with MBH Motorsports S63 Coupe Biturbo downpipes, we can help take your vehicle to Lamborghini levels of straight-line acceleration and throttle response.
By eliminating the restrictive factory exhaust manifolds, these downpipes drastically reduce backpressure and accelerate turbo spool. When paired with ECU tuning, this downpipe system delivers massive, dyno-proven gains of over 100 wheel horsepower and 200 ft-lbs of wheel torque, ensuring your S63 AMG Biturbo sits in a class all on its own.
Every set of MBH downpipes is proudly hand-fabricated in the USA using heavy-duty, 16-gauge T-304 American stainless steel to guarantee lifetime resistance against cracking, warping, and extreme exhaust temperatures. Precision-engineered for a direct bolt-on fit using factory mounting locations, this system is designed for a fast, hassle-free installation that takes less than an hour to complete.
Supercar-Level Gains: Unlocks +100+ WHP and +200+ WTQ when paired with performance ECU tuning.
Under 1-Hour Installation: Direct bolt-on design engineered for a clean, straightforward install in under 60 minutes.
16-Gauge T-304 US Stainless Steel: Handcrafted in the USA using premium American stainless steel for ultimate thermal strength and structural integrity.
Rapid Turbo Spool: Significantly reduces backpressure off the turbochargers for instant throttle response and massive low-end punch.
Exotic V8 Roar: Releases the raw, throaty roar of the 5.5L Biturbo V8 under heavy acceleration while maintaining the Coupe's luxurious cabin composure at cruise.
Engine: Mercedes-AMG M157 5.5L V8 Biturbo
Chassis: Mercedes-Benz S63 AMG Coupe (C217)
