If she hit you, then just contact her insurance company directly. You don't even have to deal with her. It will be on her liability insurance, which won't even cost her a deductible. If the repair is over $1000, then her rates will go up, however. Don't sacrifice and miss out on the LCAI. It is good.
Also, I recommend when you get it fixed if you can work it in to consider painting the rear letters "GTO" in red. I like the look of mine and get compliments.
I have the Magnaflow true X exhaust on mine and cut the mufflers from this system and went with 6" straight through bullet type mufflers. Very close to a straight pipe. Sounds really good and the popping is minimal - a little more than when it was stock, but not bad.
