Product Description

The Borla 140817 S-Type Cat-Back Exhaust System is precision-engineered for the 2017-2025 Porsche 718 Cayman and 718 Boxster, covering both the 2.0L and 2.5L turbocharged flat-four engines in Base and S trim levels. Borla's R&D team tailored this 2.25-inch diameter system specifically to the 718 platform, optimizing it for the mid-engine layout to deliver maximum exhaust flow and a dramatic improvement in sound character over the factory system. Whether you're driving with the PDK automatic or 6-speed manual, the system drops in with no cutting or welding required, using precision CNC-manufactured components for a perfect OEM-quality fit.

The S-Type sound level represents Borla's most popular performance tier - aggressive and distinctive on acceleration, yet refined enough at highway cruise speeds to eliminate the drone that plagues lesser aftermarket systems. Borla's patented straight-through multi-core muffler design, combined with Polyphonic Harmonizer Technology, unlocks hidden horsepower and torque by dramatically reducing exhaust backpressure while fine-tuning the exhaust note for a full-bodied, exotic character befitting the 718's performance credentials. The dual center-exit layout terminates in a pair of 4-inch polished round T-304 stainless tips that complement the 718's factory rear fascia without requiring any bumper modifications.

Built entirely from premium T-304 austenitic stainless steel - the same grade used in aerospace and marine applications - this system will outlast OEM components in resistance to heat, moisture, and road salt. Borla stands behind every system with their industry-exclusive Million-Mile Warranty. Note: This system is not compatible with vehicles equipped from the factory with Porsche Sport Exhaust (PSE), as it does not include the active valve solenoids required for that system's variable sound modes.
