Replace your extremely heavy restrictive factory Mercedes Benz mufflers with dyno developed and proven Fabspeed Maxflo performance exhaust system for a more muscular AMG V8 sound and significant weight reduction.


Get the authoritative muscular exhaust note that a V8 Twin Turbo AMG deserves with our Maxflo Performance Exhaust. Expect a significantly louder authoritative exhaust note, with a rumbling deep tone. 


On our DynoJet we saw max gains of 22 HP and 31 ft/lbs of TQ and peak power gains of 19 HP and 21 ft/lbs of TQ. These are great gains that you'll feel on the road, but for a massive power gain check out our XperTune.
