i am very impressed by this exhaust. installed it on my g87 m2 6mt and it sounds amazing. i previously had a g80 m3 with an awe track exhaust that cost double the price of this and this one sounds way better. i also included a comparison between this exhaust (white car) and the real valvetronic exhaust and this also sound better than valvetronic. the suppliers were great to deal with and the exhaust only took about two weeks to be made and show up at my door step. i even was able to add some custom engraving for free😜
i would definitely recommend this. fitment was better than valvetronic (quote from my mechanic who has a wholesale account with valvetronic at his shop) only thing that could be better is the clamp design but besides that everything fit great just buy new clamps or weld the exhaust and youre golden
