Except the Solo's axleback is straight pipe vs. a muffler setup. Solo themselves say the XV axleback is louder than the Mach XV catback, so that tells me that the 18" muffler would take away more sound than the stock resonator.If I had to guess, I would say the Mach XV would be closest because it is the quietest of the two. The Mach XV has the X pipe encased in an 18" muffler whereas the Thunder is 11".
From what you have stated before, the stock resonator does a lot to keep the volume in check so I would lean towards the Mach XV.
