This is a premium quality, 3 inch, lifetime guaranteed, 100% stainless steel valvetronic cat back exhaust system for Mercedes C63 AMG W205. The combination of a freer flowing exhaust and the performance mufflers provided will incur a substantial increase in sound. The exhaust system is fully mandrel bent and TIG welded in order to provide optimal gas flows and increase the performance of the vehicle. Tubing diameter is 3". The keyfob remote kit included allows you to control the sound of the exhaust. The valves are controlled by the key fob kit and allow you to switch from an aggressive sports sound to a more OEM discreet sound with the simple press of a button.
