Silencing System.

The front downpipe has broken away from the primary expansion chamber at the weld. There is also a large piece of metal which appears to be a broken baffle rattling about inside the silencer.

A local garage has made a very unsatisfactory welding job of the break, due to the aluminised finish, and it is doubtful if the repair will hold out very long.

We think it advisable to have a new downpipe and expansion box, which is integral with the second expansion chamber, sent out as soon as possible. Will you please arrange for this to be done.
