Agency Power set out to improve the amazing Porsche 997 GT3 and GT3RS. One of the biggest draw backs of the car is the heavy factory muffler. The restrictive exhaust is preventing the car from maximizing power and removes some of the exhaust sounds that make driving so pleasurable. The Agency Power muffler delete solves this by increasing the diameter of the piping, utilizing smooth mandrel bends to improve exhaust flow and removing any kind of muffler restriction from the design. The result is a more aggressive exhaust note, a lighter exhaust system and the ability for the engine to make more power, especially with supporting mods.
