This exhaust not only enhances sound but also delivers measurable performance gains. When tested, the iPE system provided increases in both horsepower and torque, enabling quicker throttle response and a more dynamic driving experience. Its distinctive tailpipes, available in titanium or carbon-fiber finishes, add a motorsport-inspired aesthetic to the vehicle's rear.

The system is designed for easy plug-and-play installation, requiring no ECU remapping, and is available in street-legal configurations with optional track-only components for those seeking maximum performance on closed circuits. With a perfect balance of sound, performance, and craftsmanship, the iPE Exhaust System is an essential upgrade for enthusiasts of the Porsche 718 GTS 4.0, Cayman GT4, and Spyder.
