Rear-ended, should I go stock or after market

I just bought my first bimmer and not a month later was hit from behind It's a black on black 335xi sedan and its all stock but not for long . I want to put an after market exhaust on it anyway for better performance looks and sound. I have always loved Borla exhausts but I was also looking at the Dinan products. Dinan is way more pricey and it doesn't look like a cat back system. Not sure which way to go.

I was also looking at different bumper covers, I would love to give the car a face lift with M3 parts. Or go with a rear bumper that has a difuser.

Any suggestions would be great! Thanks!

Wow, I know how you feel, I got rear ended as well not long after I bought mine. Not sure what you should do in terms of the rear bumper replacement. The guy that hit me paid for it however, he attempted to give me 500 bucks cash, but instead I took it right to my service center off base and had them fix it.

The bill ended up costing 1,800.00 Euro...so much for his 500 dollar attempt to buy me off, I bet his insurance was less than happy.

yea it sucks, the insurance is covering it though. I just figured if i'm putting new parts on her I might as well get something nice. I'm leaning towards the borla exhaust and a stock bumper.
