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 header fasteners and allowing a significant period of time for the chemical to lubri-cate the threads before attempting to disassemble. 

Original Exhaust System Removal

1. Unbolt the clamp located in front of the muffler assembly and remove the
hangers from rubber isolators. (See Fig. 1)


2. Using a muffler stand or an additional person to support the exhaust system, loosen and slide the clamp behind the OE muffler. Remove the hangers from the rubber isolators and remove the exhaust system from the vehicle. (See Figs. 2 & 3)  



3. Remove the original isolator bracket from vehicle and transfer to your new Borla system. (See Fig. 4)

4. Place a clamp over the expanded end of the Mid Pipe Assembly and insert the inlet into the outlet of the Front Muffler Assembly or Extension Pipe. Insert the hangar into the rubber isolator. Do not tighten the clamp.  

5. Place a clamp over the expanded end of the Muffler Assembly and insert the inlet into the Mid Pipe Assembly. Insert the hangar into the rubber isolator. (See Fig. 6) Do not tighten the clamp.

Place a clamp over the expanded end of the L/H Tail Pipe Assembly and insert inlet to the Cross Over Pipe Assem-bly. Insert hangar into installed left-side Hangar Bracket Assembly. Do not tighten the clamps. (See Fig 8)

10. Once position has been determined to be correct, tighten the Accuseal clamps to 32- 35 ft. lbs.  


11. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system. (See Fig. 10)  

12. 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.  

13. Reinstall spare tire to vehicle.

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. 

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 coat-ing 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 temper-atures.
