The Akrapovic Evolution Line Catback (Titanium) (Part #S-AU/TI/28H) is the ultimate exhaust upgrade for the 2025+ Audi RS3 Sedan (8Y FL). Precision-engineered from high-grade titanium and finished with handcrafted carbon-fiber tailpipes, this system is built for weight savings, power gains, and an unmistakable sound that amplifies Audi’s legendary five-cylinder performance.
Constructed using titanium tubes and a titanium muffler, the Evolution Line connects seamlessly to the car’s stock downpipes via a stainless-steel link pipe. The result is a system that is 36.2% lighter than stock, cutting unnecessary weight and boosting performance.
On the Akrapovic dyno, this system delivered:
+7.5 kW (10.2 hp) at 5,450 rpm
+8.8 Nm torque at 3,900 rpm
These improvements translate to sharper throttle response and stronger midrange pull, enhancing both everyday driving and track performance.
The Evolution Line is designed around the RS3’s iconic five-cylinder engine. Dual exhaust valves — cast in Akrapovic’s in-house foundry — allow the sound profile to adapt to driving modes:
Comfort Mode: Relaxed, subdued purr for daily driving.
Dynamic Mode: A sharper, more engaging tone with audible character.
Full Acceleration: A true motorsport experience with aggressive, raw sound.
Optional Akrapovic Sound Kit is available for full driver control over exhaust tones (note: fitting the Sound Kit voids the ECE type-approval certificate).
Tailpipes: Handcrafted carbon-fiber with titanium inner sleeve
Optional Rear Diffuser: High-gloss handmade carbon-fiber rear diffuser available
Construction: CNC mandrel-bent, high-grade titanium + stainless-steel link pipe
Approval: ECE type-approved for cars with Otto/gasoline particulate filter
