Inspect the GMG093 exhaust gasket, C11 clamp and GMR008 mounting rubber during installation and replace any worn, cracked, stretched or corroded components where required.

After installation, check the rear muffler and pipework for adequate clearance from the vehicle body, suspension and surrounding components. Start the engine and inspect all exhaust connections for leaks.
