BORLA PERFORMANCE INDUSTRIES 5901 Edison Dr. Oxnard, Ca. 93033 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 Cat-Back 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 Cat-Back Exhaust System.

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. Figure 1 1. Unbolt the flange shown in figure 1 located in front of the rear muffler assembly. Unbolt the flange shown in figure 2 located ahead of the front muffler assembly. Make sure to remove the ground strap also shown. Lubricate all the hangers and rubber isolators. Using a muffler stand or an additional person to hold the front muffler assembly up in place, remove the hangers from the rubber isolators and then remove the front muffler assembly as shown in figure 3. Safely lift the vehicle allowing for the rear axle to drop. Using a muffler stand or an additional person to hold the rear muffler assembly up in place, remove the hangers from the rubber isolators and then remove the rear muffler assembly as shown in figure 4.

Warning: Use extreme caution during installation. Torque all fasteners according to manufacturers torque values and tightening sequence.

Borla Performance Cat-Back Exhaust System Installation
Place the muffler assembly up into position as shown in figure 5 making sure to install the hanger into the rubber isolator. Using the hardware supplied, install the ground strap and hand tighten the flange hand tight for now. Figure 5 Place a clamp over the expanded end of the tail pipe and set it into position as shown in figure 6 installing the hanger into the rubber isolator. Do Not tighten the clamp. Check your exhaust system for proper clearance under the vehicle and also for tip alignment. Once position has been determined to be correct, tighten the Accuseal clamps to 32-35 ft. lbs. and the flange hardware to 18-22 ft. lbs. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system. Figure 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.
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

Congratulations!!!

You have completed the installation of the world famous Borla Performance Stainless Steel Exhaust System.
