Cat Back Exhaust System Installation
2014+ 5.3L Silverado Sierra
Dual Under the Bumper w/ Dual 4.0” Pro Series Tip
PN 14867 (119” WB);
PN 14869 (143.5” WB); PN 14870 (153” WB)
NOTE: During cold weather start-ups, you may experience an exhaust sound that is deeper and louder in tone than
usual. This is temporary and will diminish to normal levels once your engine has reached its normal operating
temperature.
NOTE: Immediately following the installation of your exhaust system, you may experience a trace of smoke after
initial start-up. DO NOT be alarmed. The smoke is caused by the burning of a small amount of forming oil residue
used in the manufacturing process.
7. Insert the supplied 5/16”-18 bolt through the tail pipe Wire Loop & Plate hanger and thread it into the
threaded Mounting Plate on the top of the frame.
Note: Position the driver side hanger so that it faces toward the spare tire (See Fig AA)
8. Slide a 2.5” TORCA clamp over the inlet of the driver’s side tail pipe and install tail pipe onto the over the axle
pipe. (See Fig’s BB, CC & DD) Insert tail pipe into provided rubber grommet and pre-tighten clamp at this
time.
Note: Using a soapy solution on the grommet hole will make the job easier.
9. Locate exhaust tip assemblies and slide a 2.5” TORCA clamp over expanded end of tip assembly. With the bolt
and nut facing up, snug fit the clamps on each tip assembly. Do not tighten at this time. (See Fig’s EE & FF)
10. Check the alignment of tail pipe and tips. Make sure there is at least 1.5” clearance between the tips and the
bottom of the bumper. Align tail pipe if necessary by making adjustments at the slip joints.
11. Starting from the front of the Corsa exhaust system, tighten the spherical clamp to 21 ft-lbs and TORCA clamps
to 45 ft-lbs using a torque wrench. Make sure clamps are positioned and tightened as shown. (See Fig
CLAMP)
12. It is strongly suggested that all clamps be checked and tightened if necessary after road testing the vehicle
and after the system has cooled.
