I do not know off hand what the size is. It is easy enough to measure however. If you have one of them Stanley or Craftsman racheting clamps just loosely snug it on the pipe remove from pipe then measure with a ruler. This should get you in the ball park. I know that AUTOZONE'S internet site sometime gives dimensions for exhaust pipes, tail pipes etc. Might be worth a look.

HOPE THIS HELPS
