As the title states, I bought a Two Brothers slip on for my 16 Xxc 1000. It was very difficult to get on and touches the left rear shock preload collar. I sent an email to Two Brothers and they offered to put it on their jig to see it it’s messed up but I’m pretty sure it’s their jig that is messed up. Anybody else have similar issues installing this exhaust? I don’t want to waste money shipping it to and from them if it’s a common issue.
