It sounds a little louder than stock on the video, but it so hard to tell on the computer. What is your opinion?
Definitely sounds like it revs quicker too.
It's louder and a bit deeper, but not loud by Harley standards. I'm sure it's still even legal
In the Road Glide board I've posted some stock dyno results and a video of my initial stock pipe test. I used a Radio Shack sound meter to establish the stock db baseline. As I make changes I repeat the test. When removing the cat this is what I found:
Idle with cat: 93db - w/o cat: 96db
2K RPM with cat: 102db - w/o cat: 100db
3K RPM with cat: 96db - w/o cat: 101db
4K RPM with cat: 104db - w/o cat: 105db
5K RPM with cat: 102db - w/o cat: 106db
NOTE: The meter is mounted to the right of the driver over the saddlebag pointing rearward and slightly up. These are not the db's a cop would be interested in. It's basically what the driver hears when riding.
