MPI Turbo Exhaust options?

[Attack gt]

Does anyone know of any other exhaust options for the MPI Turbo besides the trail quiet and race loud muffler options? Trail quiet is so restrictive and from what I am told, the race loud makes noticeable gains but is just way to loud for the trail. Is there anything in between? I dont mind a little noise as long as its not going to get me in trouble.

Mine sure don't feel restrictive with the MPI quite muffler actually the total opposite of that.
After driving the sled stock and then adding a MPI turbo with quite muffler the sleds an animal now, with a huge fun factor.Big driver smile.. My riding buddies tease me that they hear my waste gate coming through the woods before they hear my muffler, I think they are just jealous... However I do miss the deeper tones that are now missing do to the turbo but I can live with that with the extra power gained. I think the best sounding muffler is the Sandale for the stock sleds, they sound sweet. I have wondered what it would sound like if Sandale made there muffler fit a MPI turbo ??? Hint!

I have the Light Weight Loud muffler on my '15 RTX LE Turbo and rode in Michigan and Wisconsin with no problems with law enforcement. It's really not that loud but definitely has a nice sound.

Allen Ulmer has done quite a bit of dyno time between the 2 and the trail muffler (quiet) is more restrictive as you exceed 6#'s of boost. The race can is not that loud and I have been pulled over by the men in blue and they never asked about the muffler.

you can tell in this video that it is not that loud just a sweeter street bike sound.
