Agency Power is proud to introduce their latest performance exhaust upgrades for the 14-15 Porsche 991 GT3. These new products include a stainless steel valved exhaust system and stainless steel Headers. (Sold Separately)  The Valve Controlled Muffler & Headers enhance the flow of the exhaust yielding improved horsepower and torque. One of the exciting features about this Agency Power muffler is its ability to work seamlessly with the Porsche’s ECU to control the sound characteristics of the exhaust . When the valves are closed the system is quiet and comfortable, but when the valves are open the exhaust provides an exotic sound that makes driving your Porsche that much more of an exhilarating experience!
