How to Install Borla Touring Cat-Back Exhaust - Dual Side Exit on your F-150

Note: With a used vehicle, we suggest a penetrating spray lubricant to be applied liberally to all exhaust fasteners and allowing a signifi-cant period of time for the chemical to lubricate the threads before attempting to disassemble. 

1. Unbolt the clamp located in front of the muffler assembly and remove 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 exhaust system from the vehicle. (See Figs. 2 & 3)  

3. Remove the original isolator bracket from vehicle and transfer to your new Borla system. (See Fig. 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 Perfor-mance Exhaust Systems. Use of such tools may result in bent flanges or gasket contact areas leading to exhaust leaks. 

1. Place Front Muffler Assembly using the original hardware. (See Fig. 5) Lightly tighten the bolts.  

2. Place a clamp over the expanded end of the Mid Pipe Assem-bly and insert the inlet to the Front Muffler Assembly. Do not tighten the clamp.  

3. Install Adaptor Pipes 60556 or 60564 (if required). Place a clamp over the expanded end of the Extension Pipe and insert into outlet of the Front Muffler Assembly. Do not tighten the clamp.  

4. Place a clamp over the expanded end of the Mid Pipe Assem-bly and insert the inlet into the outlet of the Front Muffler As-sembly or Extension Pipe. Insert the hangar into the rubber isolator. Do not tighten the clamp.  

5. Place a clamp over the expanded end of the Muffler Assembly and insert the inlet into the Mid Pipe Assembly. Insert the hangar into the rubber isolator. (See Fig. 6) Do not tighten the clamp.  

6. Place a clamp over the expanded end of the Tail Pipe Assem-bly and insert inlet to the right-side outlet of the Muffler As-sembly. Insert hangar into installed right-side-side Hangar Bracket Assembly. Do not tighten the clamp. (See Fig. 7)  

7. Check tip position parallel to bottom edge of fender. Once posi-tion has been determined to be correct, tighten the Accuseal clamps to 32-35 ft. lbs. (See Fig. 8)  

8. Before starting your vehicle, make sure to check all wires, hos-es, 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 oper-ating temperatures.
