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 clamps shown in figure 1 located just under the transmission at the rear of the vehicle.

2. Using a 13mm socket, unbolt the spring hangers located just in front of the clamps as shown in figure 2. Place the bolts aside for use during the installation of your new exhaust system.

3. With a muffler stand or an additional person to hold the h-pipe assembly up into position, using a 15mm socket, unbolt the flanges shown in figure 3 located just behind the catalytic converters. Place the hardware and gaskets to the side for use during the installation of your new exhaust system.

4. Remove the h-pipe assembly from the vehicle by dropping the front down as shown in figure 4, than sliding the rear portion out of the factory over axle pipe/muffler assemblies .

5. Using a spray type lubricant, lubricate the hangers shown in figure 5 at the rear of the vehicle just above the tip assemblies.

6. Beginning with the driver’s side of the vehicle, remove the hangers from the rubber isolators and remove the muffler assembly from the vehicle as shown in figure 6.

7. On vehicles equipped with automatic transmissions, remove the passenger’s side heat shield from the fuel tank. Using a set of pliers or something similar, bend the tab down as shown in figure 7.

8.Repeat step 6 for the removal of the passenger’s side muffler assembly.

Warning: Use extreme caution during installation. Torque all fasteners 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.

1.Place a clamp over the expanded end of left (driver’s side) and right (passenger’s side) inlet pipes located on the muffler assembly as shown in figure 8.

2.Insert left (driver’s side) and right (passenger’s side) over axle pipes into their corresponding muffler inlet pipes as shown in figure 9. Do Not tighten clamps.

3.Carefully guiding the over axle pipes through the exhaust openings, place the muffler/over axle pipe assembly into position as shown in figure 10 making sure to install the hangers into the rubber isolators.

4.Re-install the H pipe assembly in the opposite order of removal and using the original hardware, reinstall the spring hangers.

5.Check your exhaust system for proper clearance under the vehicle and also for tip alignment.

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

7.Using the original hardware, reinstall the heat shield.

8.Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.

9.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 after the exhaust has reached normal operating temperatures.
