Caution!!! Never work on a hot exhaust system. Serious injury in the form of burns can result If the vehicle
has been in use and the exhaust system is hot, allow vehicle to cool for at least 1 hour. Always wear eye
protection when working under any vehicle.
Note: It is our recommendation that you use a hoist or hydraulic lift to facilitate the installation of your new
Borla Performance Exhaust System.
Taking all under car safety precautions, lift the vehicle using a hoist or hydraulic lift. Once this has been
done, you may begin the removal of your old exhaust system from your vehicle.
Note: Before removing the original exhaust system from your vehicle, please compare the parts you have
received with the bill of materials provided on the previous page to assure that you have all the parts neces-
sary for the installation of your new Borla Performance Exhaust System.
Note: With a used vehicle, we suggest a penetrating spray lubricant to be applied liberally
to all exhaust fasteners and allowing a significant period of time for the chemical to lubri-
cate the threads before attempting to disassemble.
NOTE: When you first start your vehicle after the installation of your new Borla Performance
Exhaust System, there may be some smoke and fumes coming from the system. This is a protective
oil based coating used in the manufacturing of mandrel bent performance exhaust tubing. This is
not a problem and will disappear within a very short period of time after the exhaust has reached
normal operating temperatures.
WARNING: Use extreme caution during installation. Torque all fasteners according to manufactur-
er’s torque values and tightening sequence. DO NOT use air impact tools to tighten fasteners on
Borla Performance Exhaust Systems. Use of such tools may result in bent flanges or gasket contact
areas leading to exhaust leaks.
