Query: works well but fit was off

The muffler does its job, but the o-ring together with the with the resonator pipe (also new from Walker) pushed the connection up into the frame were it rattled constantly. There was plenty of room below the connection, so there was no need to be so close. Resolved the issue by removing the o-ring and using muffler cement, which kept the connection away from the frame.
