GM Metro/Sprint 1985-1993 Repair Guide



See Figure 1

Periodic maintenance of the exhaust system is not required. However, if the vehicle is raised for other service, it is advisable to check the general condition of the catalytic converter, pipes and muffler.

Check the complete exhaust system and nearby body areas for broken, damaged, missing or incorrectly positioned parts, open seams, holes, loose connections or other deterioration that could permit exhaust fumes to seep into the passenger compartment. Dust or water in the rear compartment may indicate a problem in one of these areas. Any faulty areas should be corrected immediately.

The exhaust system consists of an exhaust manifold, heat shield, front pipe/catalytic converter assembly and a resonator/muffler/tailpipe assembly. Various flexible rubber hangers suspend the system along the underside of the vehicle.

Be very careful when working on or near the catalytic converter! External temperatures can reach 1,500°F and more, causing severe burns! Removal or installation should be performed only on a cold exhaust system.
