Porsche 991 turbo S with Evolution MotorSports EVOMS EVT640 Performance System

Added by AutomotiveUploads


The new 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 plant is capable of exuding. Our carefully engineered and thoroughly tested Performance System adds that intoxicating exhaust sound while adding the additional power punch performance enthusiasts crave.

The heart of the Evolution MotorSports engine performance System is the EVOMSit Intelligent Engine Control Module (ICM). The ICM integrates seamlessly with the OEM electronics which increases boost pressure to improve the power and torque of the turbocharged 991 3.8L engine. Fitting the ICM is simply made through a “plug and play” wire harness with OEM connectors for a trouble-free installation.

When designing our lightweight ClubSport exhaust system for the 991 turbo / S, our goals were simple. The path to get there, however, was tedious. Reengineering the OEM exhaust took careful design, craftsmanship and perseverance in order to produce something worthy of this supercar. Our exhaust system allows the engine to “sing” with melodic exhaust notes that one would expect to hear from this 3.8L flat-6 Porsche turbo engine. The reduction of backpressure from our exhaust enables the turbos to spool up faster and helps to increase overall power and torque

- Improves overall sound and performance.
- Increases HP and TQ – On average ~24 HP and 18 ft./lbs. TQ (Exhaust Only)
- Saves 13.30 pounds verses the stock exhaust system
- Retains the use of the OEM Exhaust Tips
- Attaches to the OEM catalytic Converters
- 50 state / SMOG emissions legal
- 100% Bolt on – no modifications. Easy installation
- Works with OEM headers or EVOMS ClubSport headers, Stock Catalysts or EVOMS high flow Catalysts
- 16 gauge T-304 stainless steel – mandrel bent and purge welded

The Evolution MotorSports EVT640 Performance System with 640 HP / 665 TQ is a simple yet effective way to improve the performance of the 3.8L Porsche 991 Turbo / S. Our rigorous testing, attention to details and stringent quality control make this performance system in a league of its own. We designed and tested many components for this vehicle that didn’t make it into this performance system because they didn’t add to the overall power objective we had in mind for this application. We only offer what works and we don’t waste your time and money with parts just because we can offer them to make a buck. That is not part of our business philosophy, although there are plenty of these components currently offered in the market. Included in the EVT640 performance system is all that is needed to achieve real, reliable performance without exaggerated power figures.
