GM Service Manual Online
For 1990-2009 cars only

This vehicle uses primarily rubber exhaust pipe hanger insulators to mount the exhaust system to the underbody at fixed points. Refer to Exhaust System Clearances if exhaust system noises and/or vibrations are present. Inspect the exhaust system clearance specifications anytime all or part of the exhaust system is removed and/or replaced. Inspect for missing or damaged exhaust pipe hanger insulators and/or damaged catalytic converter support bracket if the specifications measured on the vehicle are not consistent with the Exhaust System Clearances.
