Install the chrome tip or tips when your car is cold to make installation easier. As you slide the tip onto the tailpipe or muffler tip, you will meet resistance, so you want to avoid having the parts expand due to the heat.
Measure the bumper cutouts to ensure the new chrome tip fits. With the wrong-size part, you may damage the bumper or scratch the chrome. Your tip should be long enough to be seen and properly vent the exhaust.
Apply thread-lock compound to the screw threads. Slide the tip onto the exhaust pipe and position it. Tighten the screws, and check for rattling.
Check the screws in about two weeks. The thread-lock compound should keep them from loosening, but check to be safe.
