How to Install Borla Stinger S-Type Cat-Back Exhaust w/ Black Chrome Tip - Split Rear Exit (11-14 5.0L) on your Ford 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. Lubricate all hangers and rubber isolators.  

2. Unbolt the front flange bolts. Keep hardware for reinstallation of your new exhaust. (See Fig. 1)  

3. Loosen clamp on front muffler. (See Fig. 2)  

4. Remove front muffler assembly. (See Fig. 3)  

5. Using a muffler stand or an additional person to hold the exhaust system up in place, remove the hangers from the rubber isolators and remove the remaining exhaust system from the vehicle. (See Figs. 4 & 5)  

Warning: Use extreme caution during installation. Torque all fasten-ers according to manufacturer’s torque values and tightening se-quence. 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. Working on a flat surface and referring to drawing on page 2, Assemble Front Pipe and Muffler Assembly with 3” clamp. DO NOT tighten the clamp.  

2. Position the assembly over the rear axle and insert hangers into factory rubber isolators. (See Fig. 6)  

3. Assemble Front Pipe hardware and tighten hardware. (See Fig. 7)  

4. Install Hanger Bracket Assembly to driver’s side. (See Fig. 8A)  

5. Install Hanger Bracket Assembly to passenger side. (See Fig. 8B)  

6. Assemble Intermediate Pipe and L/H Tail Pipe. (See Fig 9) Position inlet pipe into left-side Muffler Assembly and insert hangers into rubber isola-tors. (See Figs. 10 & 11) DO NOT tighten the clamp.  

7. Position R/H Tail Pipe Assembly into right-side Muffler Assembly and insert hangers into rubber isolators. DO NOT tighten the clamp.  

8. Check your exhaust system for proper clearance under the vehicle and also for tip alignment. Starting at the front and moving to the rear, tighten the Accuseal clamps to 32-35 ft. lbs.  

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

10. Start vehicle and check for any leaks. If any leaks are found, determine cause (such as loose or incorrectly positioned clamp) and repair as neces-sary.  

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 coat-ing 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 tem- 

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