GRAIL Valved Exhaust System | ECE | suitable for Porsche 718 Cayman GT4/GTS

GRAIL Valve Exhaust System
suitable for Porsche 718 Cayman GT4 / GTS (incl. Spyder)

Product Description

The Porsche 718 Cayman GT4 and GTS rely on a naturally aspirated 4.0-litre flat-six with a high-revving character and direct throttle response. The mid-engine layout delivers balance and precise turn-in. The GRAIL Valve Exhaust System builds on this concept and sharpens the acoustic profile – tuned for impact and completely free of drone.

Highlights

• 4.0-litre flat-six with a high-revving character – GRAIL delivers a noticeably sporty-tuned sound without drone
• Centrally positioned Tips and mid-engine balance – GRAIL emphasises tonal clarity during throttle transitions and in the upper rev range
• ECE type-approved – no registration required* in all participating ECE countries
• Crafted from high-quality 304L stainless steel
• CNC-machined precision parts – maximum durability and perfect dimensional accuracy
• Flow-optimized pipe routing – optimal exhaust flow and temperature stability
• Developed by German engineers – the highest precision in design and manufacturing
