how loud will the 128-65117's designed for the 2010-2011 touring bikes be if put on a 2009 touring bike? I have a set on my 2011 RGU and they sound good. I notice the baffle is open and I know someone who wants a set for his 2009. I said they are going to be pretty loud do you have some actual numbers? thanks.

Your pipes on a 2009 model will be 3-4 db's louder than a 2010 or 2011 model with the catalyst in the headpipe.
If your friend is looking for the same sound levels you have, then he needs to look at the SE's P/N 128-65115 or the Double Esspresso's.

I think he wants it to be louder but not ear splitting loud. he says mine sounds too muffled that is why he was thinking the 65117's over the 65115's. This s a dumb question but to the average ear what is 3 or 4 decibles? I used to run a supermeg 2.1 on my 2004 eg and used to switch off between closed end cap and open end cap how many decible difference between open and closed end cap on a supermeg for comparisson?

The "open" vs "closed" is normaly about 3-4 db's louder.
