Akrapovic Mercedes-AMG A 45 / A 45 S (W177) OPF/GPF Evolution Line S-ME/T/1H
The Akrapovic Mercedes-AMG A 45 / A 45 S (W177) OPF/GPF Evolution Line S-ME/T/1H exhaust system is engineered to deliver an extraordinary sensory experience and exceptional performance for your AMG A 45 / A 45 S. Constructed entirely from high‑grade lightweight titanium alloys—with critical components such as the exhaust valve housings cast in Akrapovic’s in‑house foundry—and paired with high‑grade stainless‑steel link pipes, this exhaust system is designed to dramatically reduce weight and optimize exhaust flow. The result is an impressive boost in power and torque across the entire rev range, along with an aggressive, pure race‑note sound.
Advanced Materials and Engineering
Every component of the Evolution Line has been meticulously engineered to deliver peak performance:
- Titanium Construction: The main parts, including the central muffler, are made from ultra‑light titanium, significantly reducing the overall system weight from a stock 20.8 kg down to 11.2 kg—a staggering 46.3% weight reduction.
- Stainless‑Steel Link Pipes: These high‑grade pipes ensure optimal flow of exhaust gases, reducing back pressure and maximizing engine efficiency.
- In‑House Cast Valve Housings: Each side of the muffler features a specially designed exhaust valve, with housings cast in‑house to ensure precision and durability.
Dynamic Dual-Valve and Acoustic Tuning
A standout feature of the Evolution Line is its dual‑valve system:
- Dual-Mode Operation: The system incorporates two valves (one on each side of the muffler), which are regulated via a specially developed Control Kit. This allows drivers to select the level of sportiness using AMG Dynamic Select.
- Tailored Sound Profiles: In Comfort mode, the exhaust delivers a smooth, refined tone that enhances the engine’s natural timbre. In Sport mode, it produces deep mid‑range tones, and in A 45 mode, it evolves into a rewarding, aggressive roar at higher revs. The result is a pure race‑note sound that provides exceptional clarity without any drone or unwanted noise.
- Enhanced Tuning Potential: The flow path of the exhaust gases is optimized, and optional enhancements (such as the Downpipe (SS)) can further improve performance—though installing the optional Downpipe (SS) will invalidate ECE approval.
Striking Visual Impact of Akrapovic Mercedes-AMG A 45 / A 45 S (W177) OPF/GPF Evolution Line S-ME/T/1H
Aesthetics are as important as performance. The Evolution Line is finished with two pairs of exquisitely crafted tailpipes:
- Titanium and Carbon‑Fibre Tailpipes: These tailpipes feature a distinctive round design with titanium inner parts, creating a bold visual accent at the rear of the car.
- Seamless Integration: They are designed to complement optional visual enhancements, such as a hand‑made carbon‑fibre diffuser and mirror caps available in both matte and glossy finishes.
Seamless Integration and Installation
The Evolution Line S-ME/T/1H is a plug‑and‑play cat‑back system that fits directly onto the AMG A 45 / A 45 S’s stock downpipes without removing the catalytic converters. It is engineered to meet ECE type approval for vehicles equipped with an Otto/gasoline particulate filter. Installation is straightforward, typically requiring around 300 minutes by experienced professionals.
Ordering Reminder:
Due to packaging constraints, the system is split into two part numbers: S-ME/T/1H and L-ME/SS/3. Both must be ordered together. Additionally, be sure to order the correct mandatory Control Kit depending on whether your vehicle was produced before or after the mid‑2023 facelift.
