Maybe...
I rode my spouse's bike with the Trapp, to work the other day...wanted to stir up the fluids a bit.
Anyway, I have to say that the difference between the Trapp and Raask is probably bottom end torque. The Trapp gives more back pressure and probably more grunt, even with 14 disks to the bottom end. The Raask, being freer flowing, seems to perform more on the mid range and top end.
I'm thinking of modifying the optional internal baffle (that sounds like crap when installed), to provide just a bit more back pressure to the Raask.
