Valvetronic Cat-Back Exhaust System

The Stone Exhaust Valvetronic Cat-Back Exhaust System is meticulously engineered to elevate the performance and auditory experience of your Mercedes-Benz W/C/S205 C63S AMG, specifically models equipped with the M177 engine and 7G/9G transmissions. This system is the result of extensive research and development, beginning with 3D scanning and reverse engineering of the OEM exhaust to ensure a precise, 100% fitment. Key features of this cat-back system include a Valvetronic design with a remote controller, allowing you to instantly switch between ON, OFF, and AUTO modes for the exhaust valves. The AUTO mode offers customizable valve operation based on RPM. The system is built with advanced manufacturing techniques, including a 7-axis CNC bending machine for exceptional roundness and precision, and utilizes crisscross, overlapping, and direct spot welding for increased strength and endurance at critical connection points. Stone Exhaust also offers an OPF (Otto Particulate Filter) delete option, which can be included at no extra charge. This allows for seamless installation on OPF-equipped cars without triggering error codes or requiring ECU coding. The system is developed in-house, with engineers analyzing factors like pipe diameter and bending angles to optimize exhaust gas flow and performance. Compatibility is confirmed for Mercedes-Benz C-Class models with the M177 engine, including W205 C63S AMG (2014+), S205 C63S AMG (2014+), C205 C63S AMG (2014+), and A205 C63S AMG (2014+). The system comes with a 2-year warranty from Stone Exhaust.
