Exhaust System: Description and Operation

BASIC EXHAUST SYSTEM
The basic exhaust system consists of engine exhaust manifolds; y-pipe assembly, exhaust heat shields, muffler and tailpipe.

EXHAUST MANIFOLD
The engine exhaust manifolds are equipped with ball flange outlets to assure a tight seal and strain free connections.

PROPER ALIGNMENT
The exhaust system must be properly aligned to prevent stress, leakage and body contact. If the system contacts any body panel, it may amplify objectionable noises from the engine or body.

INSPECTIONS
When inspecting an exhaust system, critically inspect for cracked or loose joints, stripped screw or bolt threads, corrosion damage and worn, cracked or broken hangers. Replace all components that are badly corroded or damaged. DO NOT attempt to repair.

REPLACEMENT PARTS
When replacement is required, use original equipment parts or their equivalent. This will assure proper alignment and provide acceptable exhaust noise levels.

CAUTION: Avoid application of rust prevention compounds or undercoating materials to exhaust system floor pan exhaust heat shields. Light overspray near the edges is permitted. Application of coating will result in excessive floor pan temperatures and objectionable fumes.
