Akrapovic S-AU/TI/27H Evolution Line Titanium Cat-Back Exhaust System

The Akrapovic S-AU/TI/27H Evolution Line (Titanium) is a complete cat-back exhaust system engineered specifically for the 2022-2025 Audi RS 3 Sportback (8Y). This premium performance exhaust system is constructed with high-grade titanium tubes and muffler, connected to the vehicle's stock downpipes via a high-quality stainless steel link pipe, and finished with handcrafted carbon-fiber tailpipes featuring titanium inner sleeves.

Performance Gains:

• Power increase of 7.5 kW (10.2 hp) at 5,450 rpm
• Torque gain of 8.8 Nm at 3,900 rpm
• Weight reduction of 8.3 kg (18.3 lbs) - 36.2% lighter than stock
• Improved throttle response and acceleration

Advanced Sound Control:

Features two precision-cast exhaust valves, one on each side of the muffler, manufactured in Akrapovic's in-house foundry. The dual-valve system tailors the exhaust note across driving modes: a relaxed purr in comfort mode, an engaging tone in dynamic mode, and a full five-cylinder symphony during hard acceleration. The system works seamlessly with the vehicle's electronic actuators to adjust valve position based on driving program selection.

Key Features:

• High-grade titanium construction for maximum weight savings
• Handcrafted carbon-fiber tailpipes with titanium inner sleeves
• ECE type-approved for vehicles equipped with Otto/gasoline particulate filters (OPF/GPF)
• Direct bolt-on installation with factory downpipes
• Compatible with optional Akrapovic Sound Kit (voids ECE approval)
• Compatible with optional high-gloss carbon-fiber rear diffuser
• All necessary hardware and installation instructions included

Important Note: Facelift Audi RS 3 Sportback (8Y) models require the Control Kit (P-HF1636) to maintain proper exhaust valve operation and system functionality. If the optional Akrapovic Sound Kit is installed, the ECE type-approval certificate becomes invalid.
