I've got 2 brothers on my Valkyrie and they can be loud but not as bad as the cobra pipes, to me. I leave between 6-7 am on a Sat. ride but don't reve the bike and no neighbor issues. It's too funny that this post came up though. Today I put on some black exhaust pipes off a 2015 I got from a F6B brother in CA, Maxrider. A really good guy if you haven't met him. ( I'm a good judge of character ) I got to ride it for a few min's before the rain started but they did have a heavier growl than the stock chrome pipes. I think I'm going to really like these alot! Here is what it does for Stinger.
