Elevate the power and presence of your S-Class AMG with the Untd. Performance 200 Cell Downpipe w/ Heat Shield.

Key Features:

High-Flow 200 Cell Sport Catalyst

Built with a premium 200 cell metallic core, this downpipe increases exhaust velocity and reduces backpressure without going fully catless. Perfect for maximizing performance while keeping emissions and drivability in check—especially when paired with a Stage 1 or 2 tune.

Integrated Heat Shielding

Purpose-built thermal protection helps manage underhood temps, protecting sensitive engine bay components and ensuring reliable performance even under aggressive driving or in high-heat conditions.

Sharper Throttle, Stronger Pull

With the restrictions of the OEM downpipe removed, expect faster turbo spool, improved low-end torque, and stronger mid-to-high RPM power delivery—making your S63 feel sharper, faster, and more alive with every throttle input.

Deep, Refined Exhaust Note

The 200 cell setup adds a deeper, more pronounced growl under load while keeping the tone clean and balanced for luxury street use. You get the aggressive character of the M177 V8 without unwanted harshness or drone.

Built to AMG Standards

Constructed from TIG-welded 304 stainless steel with CNC-machined flanges for a leak-free fit and long-term durability under boost. Designed for seamless integration with both OEM and aftermarket exhaust systems.


Compatibility:

  • Mercedes-Benz S63 AMG (W222) – M177 4.0L Bi-Turbo V8
    (Fits sedan and coupe variants equipped with the 4.0L twin-turbo V8)
