The black piping definitely looks like it would connect to the resonator. the resonator helps with the emissions of your car, cleaning or something. resonator = black box that sits right infront of the front passenger-side wheel, and isnt very well protected, only thing covering it is the bumper cover. Good luck getting it all back together. btw, if ya got the $ to spend and like them, look into a full body kit. just gonna need a paint job to match, and corner+bumber lights arent too expensive, can get replacements for < $20 via Ebay.

again, Good luck bro.
