Akrapovic Exhaust System for Mercedes AMG GLA45/GLA45S/A45/A45S (H247, W177)

Perfectly designed for a stunning sensory experience, this beautifully crafted lightweight exhaust system is constructed from high-grade lightweight titanium and is finished with an eye-catching design featuring two pairs of titanium and carbon-fibre tailpipes for a stunning visual impact. A specially designed exhaust valve – with its housing cast in the in-house foundry – regulates the character of the sound and is adjusted through the use of Control Kit electronics developed in-house, allowing the driver to select the level of sportiness with AMG Dynamic Select. 

The system is an aural delight for all, with settings ranging from the comfortable everyday car mode, with a smooth sound that enhances the car’s engine tones without any discomfort or drone, to a sporty acoustic experience with deep midrange tones and a rich high-frequency sound at the top of the rev range to elevate the gear-shifting experience, providing amazing crackles at over-run. A different design, build, and configuration from the stock system means the exhaust saves weight and optimizes the engine’s power and torque levels, increasing both throughout the entire rev range, with increases of 6.4 kW at 6,400 rpm and 9.1 Nm at 6,700 rpm as measured in back-to-back runs on the Akrapovic dyno against a Mercedes-AMG A 45 using a standard stock exhaust. The flow path of the exhaust gases provides tuning potential, which can be further enhanced with the addition of the optional Downpipe (SS).

The system is ECE type approved for cars equipped with an Otto/gasoline particulate filter, but, when installing the optional Downpipe (SS), the ECE type approval for the Evolution Line (Titanium) exhaust system is no longer valid.

When ordering, please be aware that both part numbers, S-ME/T/1H and L-ME/SS/3, must be ordered because the system is split into two codes for packaging reasons.

Please notice you must order the correct mandatory Control Kit depending if your vehicle was produced before or after the facelift done in mid 2023.

Please be aware that both part numbers: S-ME/TI/12H and L-ME/SS/3 have to be ordered! The system is split in 2 codes only because of packaging reasons.

The Downpipe with Cat (SS) was tested and developed together with the Evolution Line (Titanium) exhaust system and offers an ideal upgrade to the Evolution Line (Titanium) system for further tuning. This addition is primarily designed for track use and will create a pure racing sound for the engine. Equipped with a high-flow 200 CPSI sport catalytic converter, the downpipe eliminates the OPF for a completely different sensory experience the moment the driver’s foot comes down! The sound level is noticeably increased and accompanied by a deep and powerful tone in the low and mid rev ranges, developing into a pure race-derived acoustic delight in high revs, which the occupants simply won’t get enough of! Every gear shift is full of crackling sounds, and the exhilarating tone is accompanied by an addictive burbling on every over-run in the sportiest settings. Despite being a track-oriented system, it retains all the comfort when you want it in Comfort mode, with no unwanted sounds or drone in the cabin.

When installing the Akrapovic Downpipe with Cat, remapping the ECU is mandatory to prevent potential “check engine light” warning signals.

FITMENT NOTICE: This product does not fit 2021 vehicles equipped with an Otto/gasoline particulate filter.

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.

The optional Akrapovic Sound Kit enables owners of selected Akrapovic car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovic technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver (already included in evolution system) to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller to regulate the valves.

With the use of the optional Akrapovic Sound Kit, the ECE type approval is no longer valid.
