Stainless Works Pontiac GTO 2005-2006 Headers - Manual (Page 2)

8. Install the catalytic converters (or off road pipes), the front pipes, and lastly the rear bends
with the two bolt flanges welded in place. We highly recommend using red high temp
RTV inside of each pipe joint. For the gasket on the two-bolt flange, we use red high temp
RTV, making sure the surfaces are clean and grease free. Then assemble the joint to
factory torque specs. Tighten all band clamps tight enough to prevent the pipes from
rotating.
9. The Stainless Works 3” rear pipes with the two bolt flange welded in place are much larger
than the factory two bolt flange opening-this is not a mismatch and will work fine with the
stock exhaust or other aftermarket 2 ½” exhaust systems. It will work optimally with
Stainless Works 3” exhaust system for the 2005 GTO.
10. Check all fasteners for proper torque (see your factory assembly manual for proper torque
specs).
11. Make sure to have adequate clearance around all exhaust pipes and drive car for 10-20
miles at legal speeds. Re-torque fasteners after heat cycling to allow for expansion.
