Removal and Installation The production front muffler can not be renewed as a separate section. It is necessary to renew the rear muffler at the same time. The production system must be cut to suit, (refer to Operation No. 25 204 0). For systems with an underbody catalytic converter, the front muffler must be renewed if a new catalytic converter is to be fitted, (refer to Operation No. 25 250 0). |
