Looks like everyone is keeping theirs!
I went for round titanium Quill exhausts on my 950SM (All models the same I believe).
The price attracted me and they're British made. Delivery was slow but the cans are very well made, light and best of all, run cool! They attach by means of a slip-on adapter to the three bolt end of the Y pipe. This is not the prettiest but is mostly hidden under the fairing on my bike.
After removing the SAS and EPC it runs a lot better. Easier starting, smoother throttle action and a bit of a growl/rumble too. I have the EVO2 set with the removable baffle which, if left in means no re-jetting required.
Hope this helps.
