1. Fiberglass parts need to be prepped and painted by professional body/paint shop prior to installation.
2. Thoroughly clean the inside of your exhaust cut out of any rocks, dirt, or road grease.
3. First test fit the cap onto your bumper. Cut included mounting tape into small sections and apply them to the outside edge of the cap as shown. Mounting flange may not fit flushly due to the flexability of urethane bumper, apply multiple layers if necessary.
4. Line up the cap from behind the rear bumper, apply firm pressure on the mounting flange into the surrounding bumper for good tape adhesion.
