Alright, I was getting onto 152; and as i was coming up i saw a tire (it was night) I had no time to swerve and avoid, so I had to hit it. Well, somethign underneath my car ('01 SES) is now rattling. I noticed taht some metal around the resonator is bent. The resonator itself appears ok, but it definately is rattling, and the impact sounded bad. I'll try and post some pics tommorow.
