I had V&H Ovals on my '08 SERK and liked the sound at idle, but they were a bit too loud for me and the wife.
When I bought the '09 SERG, I went with the TTS from Fullsac with their dyno proven map and their 2" baffles. I rode with them for four years and loved them. The sound was aggressive on the throttle, but would quiet down on the road and easily listen to my tunes without any issues.
Then two years ago my wife heard another slightly louder bike and asked if our could be just a bit louder. I found a used set of 2.5" Fullsac baffles, I don't think they make the 2.5" anymore. I put them right in, about 10 minutes to swap them out. The sound on idle increased and the bark was a bit more on throttle. But again at highway speeds, it's still very enjoyable to listen to our tunes without the amp wide open.
Some say the 2.5" will kill your performance, but to be honest, I've not noticed any drop in power or gas mileage.
My suggestion would easily be the 2.25" baffles. They say the most power is made with the 2" ones though. I guess that would be for standard cruising etc. If you're hot dogging all the time and hitting your rev limiter, the larger baffles may give you a bit more top end hp.
I agree, the Rinehart's are a bit too metallic sounding for me. Kind of like Flowmaster mufflers on cars, not a fan of them...
Good luck with your choice.
