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 front band clamps shown located just behind the H-pipe. Do not discard band clamps as they will be used for installation of your new exhaust. (See Fig. 1)
Figure 1
2. Loosen the clamps located just in front of each muffler assembly. (See Fig. 2)
3. Beginning with the left (driver) side, using a flat blade screwdriver, pull the clip to disengage it from the pipe. (See Fig. 3)
4. Remove the left (driver) side over axle pipe by removing the front of the pipe first then sliding it out of the muffler assembly.
Figure 2
5. Repeat steps 3 & 4 for the removal of the right side over axle pipe.
6. Lubricate hangers and rubber isolators.
7. On left (driver) side muffler assembly, remove the hangers from the rubber isolators and remove the muffler from the vehicle.
8. Repeat step 7 for the removal of the right (passenger) side muffler as-sembly.

9. Take over-axle pipe and cut the tab as shown and remove OE ball clamp. Repeat cut for other side. Do not discard ball clamps as they will be used for installation of your new exhaust. (See Fig. 4)
Warning: Use extreme caution during installation. Torque all fas-teners 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.

Figure 6
7. 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. 8)

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 per-formance exhaust tubing. This is not a problem and will disap-pear within a very short period of time after the exhaust has reached normal operating temperatures.
