Important Safety Precautions
Never work on a hot exhaust system, as serious injury can result. Always wear eye protection when working under the vehicle.
Installation Recommendations
Use a hoist or hydraulic lift to facilitate the installation. Take all under-car safety precautions, and lift the vehicle using a hoist or hydraulic lift.
Before removing the original exhaust system, compare the parts you have received with the bill of materials provided to assure that you have all the necessary parts.
