Akrapovič Evolution Line Cat-Back Exhaust System (Titanium) – 2023+ Audi RS6 Avant (C8) 4.0L TFSI
The Akrapovič Evolution Line cat-back exhaust delivers the deepest tone, highest flow rate, and largest power gains available for the C8 RS6 Avant when paired with the required Akrapovič link pipe set. Hand-crafted from ultra-lightweight titanium alloys in Akrapovič’s in-house foundry, this system reduces backpressure significantly, adds measurable horsepower and torque across the entire RPM range, and drops over 14 kg (31 lbs) of weight compared to the factory exhaust while producing an aggressive V8 soundtrack with zero drone at cruising speeds.
