This High Performance Racing Exhaust System by CAPRISTO is designed exclusively for the Porsche Cayman 986 & 987 (up to 2009).
The CAPRISTO high-performance system is engineered to enhance power, driveability, and sound quality, while also significantly reducing weight. It adheres to CAPRISTO’s philosophy of offering the best of both worlds: an aggressive exhaust note under acceleration and a more subdued sound for everyday driving.
Key Features:
-
Vacuum-Actuated Valve Flaps: These valves open and close based on driving conditions and driver input. They remain closed at lower engine speeds and during cruising for a deeper exhaust note, and open at wide-open throttle to unleash the full engine symphony.
-
Backpressure-Controlled Valves: The included Valve Controller Remote allows you to control the flaps manually. You can set the valves to open permanently or let the in-series control unit take over when the system is closed. This provides precise control based on your preferences.
-
Advanced Engineering: CAPRISTO exhaust systems are crafted using advanced 3D laser scanning, CAD design, digital prototyping, and CNC-bending/milling. Each system is made from high-grade T309 (1.4828) stainless steel, hand-polished to a mirror finish. This alloy was selected for its excellent sonic resonance, low weight, and durability, closely resembling Inconel used in F1.
Performance Headers:
- Bespoke Design: The manifolds feature custom pipe routing to maximize exhaust flow.
Sports Cats 250 Cell:
- High Flow Catalytic Converters: These converters feature a 250-cell substrate, designed to improve airflow and performance. The lower the cell count, the larger the holes, allowing for better exhaust gas flow. CAPRISTO Sports Cats are housed in 5.2-inch packages to optimize exhaust flow and valved exhaust system operation.
IMPORTANT:
- Installation: The system fits directly into existing OEM mounting points.
- Porsche 987 MK1 Cayman Installation Guide: Available separately.
- Recommended For Off-Road and Track Use Only: Replacing OEM catalytic converters may trigger a CEL (Check Engine Light). To resolve this, you may need to tune the ECU or use O2 sensor extensions
