I have had it on the bike for about a year, i havnt looked at the pipes underneath the bike for dents or anything, I know the pipes have hit a few speed bumps because my bike is lowered. The can itself has a very small indention wouldn't even call it a dent from my shoe hitting it. I can take pics. I would like to sell the whole exhaust system if im not able to just swap out cans. I was thinking around 300-400 for full setup.
