How to Install Borla Stinger S-Type Cat-Back Exhaust - Split Rear Exit on your F-150

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.
