I just changed out my exhaust tips yesterday. The easiest way is to remove the side bumper steps. I watched a couple youtube video's to figure out how. Pretty straight forward. Once those steps are out, you can easily reach the front two bolts. I recommend an air/battery powered ratchet or you'll be cranking for a while since their isn't much room back there.
Here is a link to where I bought mine. I wanted glossy black and Ebay was the only place I could find them.
