Installation


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 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 4.



Borla Performance Cat-BackExhaust 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.
