Agency Power uniquely designed this exhausts to improve the sound without stealing the already impressive performance of American muscle. Agency Power has mastered the balance between appearance and endurance while increasing  power and improving sound. The other reason a Agency Power Race Tuned Catback Exhaust for the Ford Mustang GT 5.0 is the perfect fit for your American muscle car, is because this exhaust has been designed, built and tested here in Arizona. What better way to salute your pony car then to put on a quality set of pipes?

The factory exhaust only gives you a mild purr, give your prized possession the tuning it needs to sound like the beast it was made to be. The 3″ stainless steel piping will give your Mustang the growl that will turn heads. Power gains of 10hp and 20tq to the wheels throughout the power curve, is yet another reason you need to bolt on the Agency Power Race Tuned exhaust to your 2011 Mustang GT.

Here’s a little taste of what your car could be.

And the testing to prove the power.
