AP Mufflers

Exhaust Muffler

The Porsche 997 is an easy car to make power with. However, you need to choose the correct products to gain performance properly. Agency Power has designed this muffler system for the Porsche 997 to give your car a great sound and add over 10 wheel horsepower! Tested in proper conditions on a Mustang Dynamometer, this exhaust system repeatedly added horsepower to our stock 997 Carrera. Porsche owners desire an exotic sports car sound with improved power. When you bolt on the AP Mufflers, you get better throttle response with the reduced restriction. The car will scream at the high RPM, yet have no droning sound while at cruising speeds. The Agency Power muffler kit is made from 321stainless steel. The entire system is polished. This system saves almost 15lbs over the factory mufflers! Factory tips and aftermarket tips can be used with this system. It fits with all factory hangers and mounts up to the factory or aftermarket cat pipes. Mufflers fit all Porsche 997 Carrera and Carrera S vehicles from 2005-08. NOTE: Factory Non-S Carrera Tips will need to be welded in place. All S model tips will clamp to exhaust,
