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 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. 

Original Exhaust System Removal

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

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

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

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 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.

Original Exhaust System Removal

5. Remove the exhaust cover and retaining hardware for re-installation. (See Fig. 5)  

6. Loosen and remove clamp on L/H pipe behind catalytic convert-er (See Fig. 6A). Use a metal-cutting-bladed saw, cut the R/H catalytic converter close to the weld at the Y-pipe. (See Fig. 6B)  

7. Loosen and remove (2) flange nuts from the R/H catalytic con-verter and remove from the vehicle. (See Fig. 7) Deburr the out-let side of the R/H converter.  

8. Using a muffler stand or an additional person to support the L/H crossover pipe assembly, loosen and slide the converter down. Remove the hangers from the rubber isolators and remove the L/ H crossover pipe assembly from the vehicle. (See Fig. 8)  

WARNING: Use extreme caution during installation. Torque all fasteners according to manufactur-er’s torque values and tightening sequence.

1. Orient components on floor for your Part Number referencing drawings on pages 2-6.  

2. Using the original hardware install the OE R/H & L/H catalytic converters to vehicle. Place a clamp over the expanded end of the L/H Front Pipe Assembly and install to L/H catalytic converter outlet. Insert hangers into the rubber isolator. (See Fig. 9)  

3. Place a clamp over the expanded end of the R/H Front Pipe As-sembly and install to R/H catalytic converter outlet. (See Fig. 9)  

4. Place clamps over the expanded ends of the X-pipe Assembly and insert the inlet to the L/H and R/H Front Pipe Assemblies. (See Fig. 10) Do not tighten the clamps.  

5. Place a clamp over the expanded end of both Intermediate Pipe Assembles and insert the inlet into the outlet of the X-Pipe As-sembly. Insert the hangar into the rubber isolator. (See Fig. 11) Do not tighten the clamp.  

6. Place a clamp over the expanded end of the L/H Muffler Assem-bly and insert the inlet into the L/H Intermediate Pipe. (See Fig. 12) Do not tighten the clamp.  

7. Place a clamp over the expanded end of the R/H Muffler Assem-bly and insert the inlet into the R/H Intermediate Pipe. Insert the hanger into the rubber isolator. Do not tighten the clamp. (See Fig. 12)
