The free flow Smart City and Smart Fortwo muffler has the following characteristics:

• the product has the esthetic nozzles on an exhaust pipe made of the polished stainless steel;

• the sport (free flow) exhaust system of fume removal from the engine that leads to improvement of engine operation;

• the system of installation adapted to regular standard fastenings and guaranteeing no exhaust touching at any drive;

• the built-in flame arrester and the system protecting heat-insulating layer from blowing;

• the improved low-frequency sounding of the engine operation corresponding to admissible standards on noise.

Experience of installation of direct-flow and standard mufflers for Smarts on the service centers in Ukraine shows that there is NO need for additional setup of the controller of engine. So the alarm lamp of engine malfunctions doesn't light up after connection of the sensor of free oxygen. In rare instances, when signal of malfunction is activated you must wait when it just goes out (the car will come to the mode).
