With the design of the Agency Power exhaust system for the 997 Turbo, it not only improves sound, it adds power and saves weight off the rear end. The factory system is very bulky and weighs almost 60lbs. The new Agency Power system cuts that by 50% to reduce weight on your already heavy rear engine car. Because of the reduced restriction in the high flow 200 cell cats compared to the stock 400 cell, the turbos are able to relieve exhaust gas much quicker. Agency Power uses larger 76mm piping to handle the increased horsepower. The 1 piece rear muffler design also aids in gaining horsepower by reducing back pressure with a more free flowing internal construction. As tested on our Mustang AWD Dyno, the exhaust gained 21 awhp and 32ft/lbs of torque.
