Ardent Performance Porsche 991 Turbo / S ClubSport Catback Exhaust System

The 991 Turbo / S is an amazing supercar of its own right. It is, however, lacking that punch of power and exhaust rumble we have grown to expect from a Porsche Supercar. Although the vehicle's performance and sound is somewhat reminiscent of the turbos from previous generations, in stock form it is missing the growl and grunt that this 3.8L flat-6 turbo power plat is capable of exuding. Our carefully engineered and thoroughly tested exhaust system adds that intoxicating exhaust sound while adding the additional power punch performance enthusiasts crave.

"Evolution MotorSports attacks the Porsche 991 Turbo / S with a vengeance and designs a Performance Exhaust System that not only adds a significant power and torque, it saves weight and gives this new generation Turbo the growl it's worthy of."

When designing our lightweight ClubSport exhaust system for the 991 Turbo / S, our goals were simple. However, the path to get there was tedious. Re-engineering the OEM exhaust took careful design, craftsmanship and perseverance in order to produce something worthy of this super car. Our exhaust system allows the engine to "sing" with melodic exhaust notes that one would expect to hear from this 3.8L Porsche Turbo engine. The reduction of back pressure from our exhaust enables the turbos to spool up faster and helps to increase overall power and torque.
