Making more power is a never ending endeavor.  Agency Power has taken on the challenge to squeeze out every last bit of performance from the Porsche 997 Turbo. The newest product that is under development now is a valve controlled exhaust system that will allows the 997TT to bypass the muffler for a major performance boost. Of course, the valve system will also keep the car tame and muffled when driving around town with the push of a button.

The complexity of the design is enhanced when working in the confined space of the rear engine 997 Turbo. But be assured, when the product hits the market, it will be with a show quality finish with superior performance.
