Well the insurance inspector took a look at my vehicle today. Total damages came out to $3000...$1500 of that is the stock single exhaust. Apparently the impact dented the muffler on my stock single exhaust, so the inspector was kind enough to put down $1500 for a full OEM exhaust. Thanks to that dumb girl I'll be getting a brand new Borla dual for $1339.
My impact beam was still intact (no damage) but I'm just going to pay out of pocket for the OEM hitch version.
Now I just have to wait up to 30 days because the other insured party is not returning the insurance company's phone calls.
Here's a lesson to everyone else...if anyone rear-ends you do not accept cash or let them off the hook no matter how much they beg or how little you think the damage is. I'm glad I called the police.
