Grail exhaust system suitable for Audi RS7 C8 Sportback (4.0 TFSI V8-Biturbo Mild-Hybrid) – valved exhaust system

The Audi RS7 C8 Sportback (from 2019) is the four-door coupé version of the RS6 C8: same engine, same output, different body. A 4.0 TFSI twin-turbo V8 mild hybrid with 600 hp, and 630 hp in the Performance version (from 2023). The GRAIL valved exhaust system gives this V8 the full sound Audi holds back in the standard set-up: deep, dark, powerful. Made from L304 stainless steel, CNC-machined to close tolerances, with ECE type approval - no registration required on any EU vehicle with standard type approval.

Valve control via the Audi Drive Select driving modes

The valves are controlled by the factory Audi Drive Select valve control of your RS7. In Dynamic or RS mode the valves open; in Comfort or Auto mode they stay closed.

Configurator - choose the exhaust tip finish

The system comes in three exhaust tip versions:

• Quad round 115 mm (stainless steel): four bold round tips in polished stainless steel - the classic sporty statement
• Quad round 115 mm (black): the same quad layout in a matt black finish - matches the RS black package
• Twin oval 220 × 115 mm (black): two wide oval tips in black - a near-factory look with a distinctive accent
