I'm leaning toward Akrapovic as it's street legal and i'll call the dealer tomorrow to ask them if they can install it and i can keep my warranty safe.
in my area i went to a garage the orders Akrapovic exhausts and
he said that the BMW dealer in Kuwait installed akra systems for few M5 (F10)owners and kept the warranty safe.
the stock exhaust is fine to me with Mppk but sometimes you want it to be abit louder you know :"(
sometimes i think about HFC downpipe but am not sure if will cause smoke under WOT.
