Why did you bother to remove the graphite seals from the old H pipe if they were not needed with the new Y pipe? (I left mine in the old pipe just in case I had to reinstall it for some reason, such as an inspection if I got into any legal trouble.) Also, I didn't have to remove the seat release either, I am curious why you had to do that?
Nice looking bike. How many miles are on it?
