so i was coming back up a ditch (dont ask) and ripped the bottom lip off my air dam. i think i may have f$%ked up my IC cause its whistleing to me now. how do i test for a boost leak? and where can i get replacement soft piping?

 

since your bottom tray is already off, just pull your lower piping so you can put on a rubber coupling with a end on it to pump air into the pipes and then spray with some soapy water on your i/c plumbing. for the price of those stock parts it would probably be better to just get some aftermarket piping if you find one of them to be damaged. good luck.
