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 tube applied liberally to all exhaust fasteners and allowing a significant period of time for the chemical to lubricate the threads before attempting to disassemble.

1. Loosen the clamp shown in figure 1 located just behind the y pipe assembly.
2. Loosen the clamp shown in figure 2 located just in front of the muffler assembly.
3. Using a flat blade screwdriver, pull the locking clip to disengage it from the pipe. Remove the over axle pipe by first removing the front of the pipe from the y pipe as shown in figure 3 then remove it from the muffler assembly.
4. Remove the hangers from the rubber isolators and remove the muffler from the vehicle as shown in figure

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-BackÔ Exhaust System Installation

1. Place a clamp over the expanded end of the Borla muffler assembly and set it up into position as shown in figure 5 installing the hangers into the rubber isolators.

2. Place the original clamp over the front of the over axle pipe and set it into position by first installing the rear of the pipe into the muffler assembly than install the front onto the y pipe.

3. Check your exhaust system for proper clearance under the vehicle and also for tip alignment.

4. Once position has been determined to be correct, tighten the Accuseal™ clamp to 32-35 ft. lbs.

5. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.

6. Start vehicle and check for any leaks. If any leaks are found, determine cause (such as loose or incorrectly positioned clamp) and repair as necessary.

Congratulations, as shown in figure 6 you have completed the installation of your new Stainless Steel Borla Performance Rear Section Exhaust System.

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.
