Looking to change the silencer on my M2, presently fitted with standard can.

I've read that the 2 favorites are the Buell Pro pipe or Vance & Hines, but I see that Quill make one for the M2.
Although i've read bad things about the xb version, is the tuber one any better?

I was only looking at the Quill as I imagine would be slightly quieter when fitted with the quiet insert than the other two.
Are there any others to consider?
Thanks

Got a V&H on mine.... Plus a stage 2 kit..... Seems to work OK.

There is a pro race kit in the for sale section that will fit an M2 ( I think) tis on e bay and is complete with headers
