Driving the Porsche GT3 is extremely fun with its high revving naturally aspirated power band. However like other Porsche cars, it just does not have that aggressive sports car sound. Especially one for a car that is supposed to be oriented for the track. This is why we have developed the new Agency Power Valved Exhaust System, which is a direct replacement for the factory muffler.
This Agency Power Valve Exhaust muffler features precision mandrel bent tubes, T303 high quality stainless steel construction, beautiful TIG welds and integrated exhaust valves that allow you to change the sound characteristics of the exhaust with a push of a button.
