Got a rattle in your GL10 crossover pipe?

[scoobiedubie]

If you have a rattle but no leak, try this.  The rattle comes from loose weld material rattling around inside the heat shield.  Remove the pipe and by shaking it, try to locate the area where the metal pieces have room to move.  Then, carefully grind a hole in the heat shield, where you think that the metal piece can be coaxed to leave the heat shield.  Then no more rattle.
