Product Details:

Since their beginnings in the Porsche tuning market, Agency Power has always strived to create the finest products at a fair price while proving them with their own project vehicles. The Porsche 991 Turbo tuning components are being designed and tested here with their own vehicle. Creating an OEM replacement exhaust may seem easy, but there are key elements to take into consideration as well. There is a fine balance between performance and sound. With the engineering Porsche has done in the new 991 including the economy mode, drone will be even more present than before. If you are not in Sport Mode, the car can be running at 1500rpm as your cruising at 40mph down the road. Previous 997 Turbo had a drone spot of around 2200-2800rpm. So reducing backpressure to gain performance while keeping a clean sound for daily driving is priority one!

Typically an X-Pipe design gives the car a bit of a muffled tone. That is because of the turbulence where the X junction is merged. Many people like this sound, however the turbulence can affect performance. The only time AP heard a significant sound change is with a titanium exhaust because of how the material resonates the sound. They chose to do their system in a full 3 inch stainless steel as a U bend with dual resonators. From the catalytic converter, the exhaust gas goes through 1 resonator, U turns through another resonator, and then out the exhaust tip. This gives each turbo its own full 3″ outlet. With the U-turn and 2 resonators, this should create a clean sound. Utilizing this with the stock catalytic converters will give some increases over stock while keeping you emission clean and CEL free. The exhaust is designed to work with the OEM or OEM style tips available.

As tested on their Mustang AWD Dyno, we compared the 991 Turbo with the new Agency Power muffler to the stock muffler system. The muffler freed up exhaust flow quite a bit gaining almost 40 ft/lbs of torque at 4100rpm. This is the peak torque and where the turbochargers come on full blast. Horsepower peak gain was approximately 20 awhp at 5000rpm. The new Agency Power mufflers weigh in at 19.65lbs where the stock is 24.5lbs, saving you about 5lbs off the rear end. Providing even faster turbo spool up and larger top end gains is possible with the combination of our Agency Power headers and cat delete pipes.
