help! I hope to take delivery of my new nrs on friday the 20th if it shows up from kansas city. One of the changes that I am thinking about is the exhaust. I am told that it is too quiet for this bike and it needs to be louder, yet not obnoxious. Does anyone have any ideas or has anyone replaced or modified theirs. This is my first HD and my first bike in 13yrs. Believe it or not, this was my wifes idea for my 40th! Please reply if any info is avaliable. THANKS
