During and after install, wipe off all assembly and shipping particles from the
exhaust. If dust is not wiped off, once the exhaust gets hot, the particles burn onto
the stainless steel finish and become permanent.
Ensure the exhaust tips on both sides protrude from the bumper evenly and are not
touching any body panels.
Apply anti seize to all assembly bolts to allow for ease of removal.
