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. Unbolt and remove the two clamps shown in figure 1 just in front of the muffler assembly.  

2. If the clamps have worn a groove into the muffler inlet pipes, it may be required to cut and spread the inlet pipes as shown in figure 2 in order to remove the exhaust system from the vehicle.  

3. Lubricate all hangers and rubber brackets.  

4. Using a muffler stand or an additional person to hold the exhaust system in place, remove the hangers shown in figure 3 from the rubber brackets.  

5. Remove exhaust system from vehicle as shown in figure 4.  

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. If any welding is performed, protect vehicle brake, fuel, vacuum or similar lines. Always check for any damage after welding has been done. Also check inside vehicle for damage to such items as carpet, inner liner, etc. Always have a class C fire extinguisher and a bucket of water available during any welding process. 

1. Place the muffler assembly in position as shown in figure 4 and install the hangers into the rubber brackets. DO NOT tighten the clamps.  

2. Place the left and right tail pipe assemblies together using the hardware supplied. Hand tighten the hardware for now.  

3. Place a clamp over the expanded end of both left and right tail pipe assemblies and install them into position as shown in figure 6. DO NOT tighten the clamps.  

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

5. Once position has been determined to be correct, secure the hardware to 14-16 ft. lbs. and tighten the Accuseal clamps to 32-35 ft. lbs.  

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

7. 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. 

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