Am I correct in assuming that smaller baffles are quieter than larger baffles? 1.75" would be quieter than 2"? I hope it's not the other way around.

 

Yes the 1.75" should be quieter than the 2".

I purchased a set of used slip-ons for a good price last year but they had 1.75" baffles and I have now ordered 2.50" baffles for some more sound.

 

I have a set of rush slash downs that came with 1.75 baffles but they were too quiet so i ordered 2.25 baffles and only installed one baffle on the right side pipe and got a much better sound (louder)and also the bike runs smoother. I took these off the bike because i just traded for a 2010, they were on a 07 ultra so now i will sell them if anyone is interested.

 

Thanks bman.
