Anyone try these on an M8 Touring bike? How do they sound?

[Grof]

don't have a M8 , but have TH on my cvo rk and dyna nothing beats TH in sound and performance ( DnD is coming closer and closer they are almost neck in neck.... had it too...)

I don't have an M8 either but have a set on a otherwise all stock '12 RG.  Sounds great , occasional pop when shifting is all
