Have 2 quiet Mpi mufflers here. I Love the fact that they are quieter then stock. Stealthy
Check out our YouTube channel if you want to hear them from the drivers seat.

I see that the gen 2 mpi quiet muffler is different. But I'd imagine it's just as quiet?
I have one also but opted for the sweet howl of the race muffler - I do swap them out for night riding though

I was thinking it would be nice to have both. Is it much work swapping them?

nope under 5 minutes just open the panel and 3 bolts, I have the reusable gasket - and it sounds soooo good it is not anywhere as loud as the muffler on the D&D xf1100 sleds I have run against
Here is a pic of the flange with the 3 bolts

I'm kinda wishing my sled just came with the loud one. When I go with my cat buddy with his tucker I can't hear myself think. I need to put up a fight.

th.
The mpi light weight muffler surprisingly isn't very loud, it sounds real nice but certainly won't get u into trouble, the turbo helps to quiet things down, on an n/a sled that style muffler would be much louder.
No I got pulled over in the UP late last season and they never said a thing about the muffler - now speed was another issue $550 later 
Here is one with a guy standing next to me filming
