Akrapovic Mercedes-AMG A 45 / A 45 S (W177) Evolution Line S-ME/T/1H
The Akrapovic Mercedes-AMG A 45 / A 45 S (W177) Evolution Line S-ME/T/1H exhaust system is designed to deliver a stunning sensory experience and extraordinary performance enhancement for the Mercedes-AMG A 45 and A 45 S models. Crafted from high‑grade lightweight titanium, every element of this exhaust is engineered to reduce overall weight while increasing power and torque throughout the rev range. With complex parts produced in the Akrapovic in‑house foundry—including valve housings and other intricate components—this system represents the pinnacle of performance exhaust technology.
Superior Materials and Engineering
At its core, the Evolution Line system is constructed from ultra‑light titanium alloys, chosen for their exceptional strength‑to‑weight ratio and superior heat resistance. The main parts, including the central muffler, are manufactured from high‑grade titanium, ensuring durability under the most demanding driving conditions. The link pipes, crafted from high‑grade stainless steel, provide optimized flow of exhaust gases from the downpipes to the muffler, lowering back pressure and enhancing engine breathing. Complex components such as the titanium housing of the exhaust valves and the outer shell of the tailpipes are precision‑cast in Akrapovic’s own foundry, guaranteeing consistent quality and performance.
Dynamic Sound Tuning with Dual-Valve Technology
The Evolution Line system is not just about performance—it’s engineered for a superior auditory experience as well. Each side of the muffler incorporates a specially designed exhaust valve, with housings cast in‑house, that tailors the sound output. These valves are controlled via a dedicated in‑house developed Control Kit, which seamlessly integrates with AMG Dynamic Select. This technology enables the driver to select from multiple sound settings:
- Comfort Mode: Provides a smooth, refined tone that enhances engine notes without introducing any drone—a perfect setting for long journeys.
- Sport Mode: Delivers a robust, deep mid‑range tone that reflects the engine’s power potential.
- Cupra (or high‑performance) Mode: When engaged, the valves produce an aggressive, race‑inspired roar that transforms the exhaust note into a pure, exhilarating race‑note experience.
The system’s acoustic design is further refined by the inclusion of two tuned resonators, developed specifically for this engine. These resonators ensure that the deep, sporty tone remains free of unwanted drone and streaming, resulting in an engaging, well‑balanced sound across all driving modes.
Striking Visual Impact of Akrapovic Mercedes-AMG A 45 / A 45 S (W177) Evolution Line S-ME/T/1H
Visually, the Evolution Line is as impressive as its performance. The exhaust is finished with two pairs of exquisitely crafted tailpipes that combine titanium with carbon‑fibre. These tailpipes are designed with a distinctive round look and feature titanium inner parts for added contrast and durability. Not only do they contribute to the overall weight reduction, but they also enhance the vehicle’s rear aesthetics. For those seeking an even more dramatic finish, optional carbon‑fibre diffusers and mirror caps are available, offering matte or glossy finishes to perfectly complement the Evolution Line’s aggressive design.
Performance Gains and Installation
Extensive testing on the Akrapovic dyno has demonstrated that the Evolution Line S-ME/T/1H exhaust system increases power by +6.4 kW at 6,400 rpm and torque by +9.1 Nm at 6,700 rpm compared to the standard exhaust. The improved flow and reduced back pressure contribute to enhanced throttle response and overall engine efficiency, making the car more dynamic on both the street (in appropriate settings) and on the track.
Designed as a plug‑and‑play cat‑back system, it fits directly onto the Mercedes-AMG A 45 / A 45 S (W177)’s stock downpipes without removing the catalytic converters. Installation is straightforward, typically taking around 180 minutes, making it an ideal upgrade for enthusiasts who value both performance and ease of installation.
