Akrapovic S-AU/TI/23H 22-24 Audi RS3 Sportback Evolution Line Catback

Key Specifications

• Material: High-grade titanium muffler and tubing
• Link pipe: Stainless steel
• Tailpipes: Handcrafted carbon fibre with titanium inner sleeve
• Vehicle: Audi RS 3 Sportback (8Y) 2022–2024
• Homologation: ECE Type Approved (subject to configuration)
• Weight reduction: Approximately 36–44% lighter than the OEM system
• Power gain: +10.2 hp (7.5 kW) at 5,450 rpm
• Torque gain: +8.8 Nm at 3,900 rpm on Akrapovič dyno testing  

Sound Characteristics

The system uses dual exhaust valves cast in Akrapovič’s in-house foundry:

• Comfort mode: Deep, refined OEM+ tone.
• Dynamic mode: Noticeably more aggressive with the iconic Audi 5-cylinder warble.
• Wide-open throttle: Much richer and sharper than stock without excessive drone.  

Community feedback from RS3 owners generally describes it as one of the best-sounding premium systems for the 8Y platform, particularly because the titanium construction adds a distinctive metallic tone while retaining daily-driver refinement.  

For an Enthusiast Perspective

The Akrapovič sits in the same category as premium brands like:

• Akrapovič
• Milltek Sport
• Armytrix
• AWE

For the RS3, however, Akrapovič is often considered the benchmark OEM+ exhaust because it delivers:

1. Significant weight reduction.
2. Excellent fit and finish.
3. ECE legality.
4. Improved five-cylinder sound without becoming obnoxious.
5. Strong resale value.  

Verdict: If budget is not the primary concern, the S-AU/TI/23H is arguably the most complete exhaust upgrade for the 8Y RS3. It focuses on sound quality, weight savings, and factory-level refinement rather than chasing maximum volume.
