Akrapovič Evolution Line (Titanium) slip-on system for the 2021 Mercedes‑AMG G500/G550 (W463A) uses high-grade titanium to reduce weight roughly 45% versus stock while routing dual tailpipes and integrating exhaust valves for a deeper, sportier tone. It increases power and torque across the rpm range. Fitment requires specific Mercedes options or additional OEM parts; not emissions compliant for street use.
