Chrysler Front Wheel Drive Cars 6-CYL 1988-1995 Repair Information

Front Pipe or Y-Pipe

Print

The Monaco and Premier vehicles are equipped with a front Y-pipe which connects directly to the two exhaust manifolds. The other vehicles covered by this information, however, are equipped with a single front pipe which connects to the rear exhaust pipe only. A cross-over pipe directs the exhaust gases of the front bank of cylinders from the front manifold to the rear manifold. For the removal of this cross-over pipe, refer to the exhaust manifold procedures found earlier in this section.
