Borla Performance - Bill of Materials
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 Rear Section 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 necessary for the installation of your new Borla Performance Rear Section Exhaust System.
Original Exhaust System Removal
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 lubricate the threads before at-tempting to disassemble.
1. Lubricate all hangers and rubber brackets.
2. Loosen clamp on rear muffler assembly. Remove the two hangers located on the rubber brackets and remove this assembly from vehicle. (See Fig. 1)
3. Loosen clamp on front muffler assembly. Remove the two hang-ers located on the front muffler assembly from the rubber brack-ets and remove this assembly from vehicle. (See Fig. 2)
4. Original system removed. (See Fig. 3)
Warning: Use extreme caution during installation. Torque all fasteners according to manufacturer’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.
Borla Performance Cat-Back Exhaust System Installation
1. Place a clamp over the front pipe. (See Fig.3)
2. Insert the expanded-end of the front muffler assembly into pipe. Insert hangars into rubber isolators. Lightly tighten clamp. (See Fig. 4)
3. Place a clamp over the tailpipe assembly and place into position installing the hanger into the rubber bracket. DO NOT tighten the clamp. (See Fig. 5)
4. Check your exhaust system for proper clearance under the vehicle and also for tip alignment.
5. Once position has been determined to be correct, tighten the hard-ware at the flange securing the muffler assembly and the two clamps to 32-35ft. lbs. (See Fig. 6)
6. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.
7. Start vehicle and check for any leaks. If any leaks are found, deter-mine cause (such as loose or incorrectly positioned clamp) and re-pair as necessary.
Note: When you first start your vehicle after the installa-tion 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.
