Akrapovič Mercedes CLA 45/CLA 45 S AMG (C118) 2023-2024 Evolution Exhaust System
The Akrapovič Evolution Line (Titanium) exhaust system is masterfully designed to deliver a full sensory experience, both in terms of performance and sound. Constructed from high-grade lightweight titanium and finished with a striking combination of titanium and carbon-fibre tailpipes, this system not only enhances the vehicle’s aesthetic appeal but also significantly improves performance. The specially designed exhaust valve, housed in a casing cast at Akrapovič’s in-house foundry, enables precise control over the exhaust sound. This is achieved via the Control Kit electronics, which integrates seamlessly with the AMG Dynamic Select system, allowing the driver to adjust the sound profile to match different driving modes.
Key features include:
- Sound versatility: From smooth, refined tones for everyday driving to a sportier, mid-range growl and exhilarating high-frequency sound at higher revs. This setup ensures no discomfort or drone while cruising, and thrilling crackles during deceleration.
- Performance gains: A power increase of 6.4 kW at 6,400 rpm and a torque boost of 9.1 Nm at 6,700 rpm (based on dyno tests against a standard stock exhaust on a Mercedes-AMG A 45).
- Lightweight build: The titanium construction not only reduces weight but also optimizes the engine’s power and torque throughout the rev range, enhancing driving dynamics.
Optional Enhancements:
- Downpipe (SS): The system’s flow path can be further optimized with the optional downpipe, which unlocks additional tuning potential. However, please note that installing the downpipe will invalidate the system’s ECE type approval.
Fitment & Ordering Notes:
- This exhaust system is suitable for CLA 45 S Shooting Brake models.
- For vehicles manufactured after a facelift, the mandatory Control Kit (P-HF1528) must be ordered for compatibility.
This system offers an optimal combination of improved power, distinctive sound, and refined aesthetics, making it a highly desirable upgrade for the Mercedes-AMG A 45 and CLA 45 S models.
