I have purple hornies on mine, I believe they are the same as cherry bombs, they are short straight thru glass pacs. They are unbelievably loud when you get on it and have to be careful where you are when you do. They snarl and bark real load and could get you a ticket if you really stand on the gas. Now I wish I had bought some long smittys instead, but so much for hind-site.
If your lookin for loud these are the babies...Vernski
