Got a sound video?
Thank you for the how to write up. I have a 2015 with Ivan ECU flash and just ordered my akrapovic header, leaving stock cans(for now) My question... Did you do anything to the air box hoses? Block off plate? I can't seem to find any clear direction on this other than stick a marble in it. Even knowing where and which hose to block off. Also did you do the air box mod? Drilling extra holes into it? Any direction on that?
Again thanks for the tips, I will for sure have them handy.
