Akrapovič Evolution Line (Titanium) – Mercedes-AMG A 45 / A 45 S (W177) – 2021 – OPF/GPF

Article number: S-ME/T/1H

The Akrapovič Evolution Line (Titanium) for the Mercedes-AMG A 45 / A 45 S (W177) is perfectly designed for an astonishing sensory experience. This beautifully crafted lightweight exhaust system is constructed from high-grade, lightweight titanium and finished with a striking design featuring two pairs of titanium and carbon fiber tailpipes for a stunning visual impact.

A specially designed exhaust valve – the housing of which is cast in Akrapovič’s own foundry – regulates the sound character and is adjusted via in-house developed Control Kit electronics, allowing the driver to select the level of sportiness with AMG Dynamic Select.

The system is an auditory delight for everyone, with settings ranging from the comfortable daily mode with a smooth sound that enhances engine notes without any discomfort or drone, to a sporty acoustic experience with deep midrange tones and a rich high-frequency sound at high RPM to elevate the shifting experience, with great crackles on throttle lift-off.

A different design, construction, and configuration than the original system means that the exhaust system saves weight and optimizes the engine’s power and torque levels, with increases throughout the entire RPM range. The increases of 6.4 kW at 6,400 rpm and 9.1 Nm at 6,700 rpm were measured in back-to-back runs on the Akrapovič dyno against a Mercedes-AMG A 45 with a standard exhaust.

The exhaust gas flow path offers tuning potential, which can be further enhanced with the addition of the optional Downpipe (SS).

This system features ECE type approval for cars with OPF/GPF, but installation of the optional Downpipe (SS) will invalidate the ECE type approval.
