GRAIL Valved Exhaust System | ECE
suitable for Porsche 911 GT3 RS (991.1)

The Porsche 911 GT3 RS of the 991.1 generation uses a 4.0-litre flat-six, a considerably firmer set-up and noticeably more downforce than the GT3. Acoustically the OEM system falls short of that brief. The GRAIL valved exhaust system audibly sharpens the naturally aspirated flat-six and emphasises the dry, hard tone in the upper rev range that matches the track ambition of the RS.

Highlights

• Dry, hard four-litre flat-six tone with emphasis in the upper rev range
• Track-ready acoustic edge, dialled back for everyday use via the valve
• Designed around the 4.0-litre naturally aspirated engine and the 991.1 RS rear end
• ECE type approval for road use – no individual approval required* on EU vehicles
• Handcrafted in Germany from L304 stainless steel
• Solid stainless steel valves CNC-machined from billet for lasting function

This exhaust system holds an ECE type approval and therefore requires no individual approval* for road use.

*Applies to vehicles with EU registration in standard condition. Imported vehicles and combinations with further modifications (e.g. power upgrades, intake systems) may require separate certification. Please contact our support: [email protected]
