I hope this is not a dead question, but I just recently purchased a 2015 M90 and it's way to quiet for me. I been searching the net for some pipes and I cant seem to find any to match this year. I would like to know if anyone knows a site or anything where I can buy some louder pipes for my bike. Or should I say, that will fit my bike?

 

"Try Freedom Perform". they seem to have nice exhausts for the M90 but their customer service is atrocious. Good luck.
