Thank you Artemis for the info on removing the blocking plate (flap).

I had my installer return the 1M with the installed (but muffled) Akrapovic exhaust system and I was confused as hell as to why the system sounded so unremarkable.

After taking it back and showing Figure 27 on Page 34 then having them grind that piece off to get air flowing to the outer tips of the exhaust, the unit sounds amazing and I am so happy of the upgrade.

Thanks again!
