See you have MGS true duals... I googled em can't hardly find anything on them. Do you have a clip of how they sound?
MGS is one of the more recent arrivals on the scene for TD's. I cannot say enough about these pipes, actually - they sound awesome and look amazing! They were the first set my dealership installed - and everyone in the shop raves about the sound, fit and finish.
I don't have a sound clip of them my bike, but here is a link you might want to check out on YouTube. It will at least give you an idea:
I have a friend who runs Rinehart's on his RKC. I think my MGS pipes sound deeper than his Rineharts and have a little more attitude when you roll on the throttle. That said, when cruising down the highway, they're mellow enough for me to be able to hear my tunes.
Here are some additional pics of my bike with the MGS pipes installed. Let me know if you have any other questions!
