2005-07 Cadillac STS V8 PN 14157 Exhaust System Installation

Exhaust System Removal:
1. Measure 1.5” for STS (See Fig. A) or 9” for SRX (See Fig. B) before the driver side muffler inlet weld. Using a chain cutter or saw, cut the rear muffler off at this measurement.
2. Remove the hanger on the inlet side of the muffler from the rubber isolator.
3. Remove both hangers near the factory tips from the rubber isolators.
NOTE: Be sure to save all rubber isolators from the vehicle. They will be used to install the CORSA Performance exhaust system in later steps.
4. Repeat steps 1-3 for the passenger side muffler.

CORSA Performance Exhaust System Installation:
1. Remove all exhaust system components from the shipping cartons, including clamps. NOTE: There are two 2.5-inch clamps supplied.
NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the TORCA band clamps and flange bolts. Failure to follow this procedure can cause nuts to seize on clamps and potentially destroy threads. After applying anti-seize lubricant, be sure to thoroughly clean hands as lubricant will tarnish stainless steel.
2. Locate the driver side muffler assembly and one 2.5-inch clamp. Align the clamp as shown
3. Slide the inlet of the driver side muffler over the cut end of the factory pipe. Have the clamp in position on the muffler assembly, but do not tighten yet. (See Fig. G).
4. Slide the two hangers near the tip into the respective rubber isolators. Spraying the hanger with soapy water will aid the installation. (See Fig. H).
5. Slide the hanger on the inlet side of the muffler into the rubber isolator.
6. Repeat steps 1-5 for passenger’s side.
7. Visually inspect the exhaust system position, tip alignment, clamp orientation (see exhaust system adjustment section) and exhaust pipe clearances. Make any necessary adjustments at the various slip joints.
