Cutting the stock mufflers in half results in the worst possible sound you can produce on these bikes...unless of course you happen to think that a pair of dueling chainsaws in dire need of maintenance is a good sound. For the rest of the world, it both looks and sounds like crap.
I bought my second Rebel "modified" as such and the first thing I did was cut the rest of the muffler off and mate some universal mufflers to the head pipe.
I hole-sawed the rear baffles out of another and that had a nice note to it too.
No matter what route you opt for, rejetting doesn't become an issue until you alter the intake...although cutting off too much exhaust will ruin your valves and the only fix for that is restoring some semblance of exhaust volume (cubic space, not sound level). BTW, that same cubic space will define the high or low pitch you may be seeking, more space yields a lower tone and less space yields a higher tone...think of it as a pair of soda bottles, one filled 3/4 full of water and the other filled 1/4 full. Blow across the tops, the one with more air space has a lower note.
"Ride Safe, Chop Safer" Motorcycles are not unsafe. However; they are extremely unforgiving of inattention, incompetence, ignorance, and stupidity.
Dismantling, sawzalling, and rattle canning does not make a bobber.
Those are STEPS toward customizing, not customizing unto itself.
