Never done it, I'll bet it messes with the Stage 1 which is already a tad on the lean side. They'll be loud as hell and I'm pretty sure your going to kill some of your low end. If'n it was me I'd leave well enough alone, or if it was to quiet for my taste I'd find some different mufflers.
I took the baffles out of my ovals and they were way too loud and they sound terrible. I too am on the quest for a little better sound but I can guarantee you that you won't be happy with the sound of the ovals without baffles.
to me the ovals sounds great with true duals, pretty good with stock headpipes, and with no baffle sounds like a garbage can strapped on the pipes. just my .02 though i know some guys will like that sound.
GLACIER... don't do it! Generally the 'true-duals' cause more problems than not. Think about it, the rear cylinder exhaust has to make an immediate u-turn right out of the exhaust port, which in no way will match the flow characteristics thru the smooth bends of the front head exhaust. The idea is to MATCH exhaust pressures, which is somewhat achieved by the 'connected' type system already on the bike.
At the very least you will need some sort of adjustable fuel mixture device (H-D RaceTuner is THE MOST adjustable) and some dyno time to TRY and get it dialed-in. Go to the drag strip... you won't see that type of exhaust on ANY draggin dresser.
Thanks HawgDoc i appreciate your feed back, along with everybody elses
advice. I am going to leave them and learn to enjoy the sound. It is an awesome 05 Ultra Classic, Glacier white, and chromed to the Max.. Thanks
