I don't like slip on's, but the Rush's do not sound bad at all. Why are you not installing them yourself? Slip on's have to be one of the most simple jobs on the bike.
Lots of options to tailor the sound. As others have said you can go louder than stock at 1.75 all the way to setting off car alarms at 2.25. I have the 1.75 and like the sound at all RPM's.

True that. Hardest part of the job is getting the old ones off.
