Mercedes-Benz CLA 45 S AMG 4MATIC + is a whole new breed in automotive world. It created a hyper hatch class with no rival to match it’s performance! And so Akrapovič engineered an exhaust system to match the sound with the performance! Providing a stunning sensory experience, this lightweight exhaust is beautifully crafted from high-grade titanium and finished with an eye-catching design of two pairs of titanium and carbon-fibre tailpipes. The exhaust valve – with its housing cast in the in-house foundry – controls the personality of the sound and is controlled with our own valve regulation through in-house developed Control Kit electronics. It enables the driver to select the level of sportiness through AMG Dynamic Select from comfortable every day car with smooth sound that enhances the car’s engine tones without any discomfort or drone for the occupants to race ready acoustic experience with deep midrange tones and rich, high frequency sound at the top of the rev range to elevate gear shifting experience with amazing crackles at over-run! Lighter than stock due to the use of titanium and a different configuration, the design and construction of the exhaust leads to optimization in the power and torque levels throughout the entire rev range with 6.4 kW at 6400 RPM more and with 9.1 Nm at 6700 RPM more. The optimized flow path of exhaust gases provides greater tuning potential, something that can be realized further with the addition of the optional Downpipe set (SS).ECE type approval for cars equipped with Otto/gasoline particulate filter.When installing the optional Downpipe set (SS), the ECE type approval for the Evolution Line (Titanium) exhaust system is no longer valid and the ECU must be remapped.Please be aware that both part numbers: S-ME/TI/12H and L-ME/SS/3 have to be ordered! The system is splitted in 2 codes only because of packaging issues.
