These are the ones I just had installed on my 2012 Speedmaster:
The Stainless Rides are priced similarly to the other pipes out there - I purchased from Fast Eddy and had them at my door in less than a week. I really like the purr and grumble of these -- not too loud, not too quiet. I also got the air injection kit and airbox removal kit done on the bike.
Once I get the bike back from the shop (it's still their waiting for a replacement starter relay switch that went bad
), I'll do my best to record it and upload.
