    Agency Power releases Porsche 991 Carrera and Carrera S X-pipe and cold air intake - Dyno results

    More mods for the Porsche 991 Carrera and Carrera S courtesy of Agency Power. The two modifications you see below are an X-pipe exhaust upgrade and a cold air intake. The X-pipe retails for $1,300 which is not cheap but not terrible by any means in the Porsche exhaust world. It is definitely worth the money as although the peak power gains are only three horses at the wheels the area under the curve gained is quite large. Average power goes from 228 at the wheels to 254 at the wheels and average torque from 257 wheel to 287.

    Those are some healthy gains. What about the intake? Gains from a peak of 347 wheel horsepower and 287 wheel torque to 353 wheel horsepower and 291 pound-feet of wheel torque. Combining the two is definitely a good idea.

    Now take all of these modifications and add on the Agency Power headers plus an ECU tune for solid bolt on gains and a transformed car.

    Pictures, videos, and dynographs below.

    Nice gains for bolt ons. When you factor in the price of the car, these mods are pocket change. Well worth it IMO

    Whats up with the power dip at ~4500 rpm?

    I don't know but the X-pipe minimizes it the stock power dip is bigger and earlier. Ugly curve...

    I'd get all their mods if I had it, no question.
