You would have to provide sufficient proof that the vehicle was modified in Canada before going across the border, ie. dated receipts. They can be sticky as a motherf'er when they want to be. For my stereo I didn't have receipts for anything but hardware and they wanted proof of installation. I had to get my sis to go to my place sort through my computer and burn a cd of photos detailing the full install. Meanwhile here's me sitting at the border for 3 hrs looking like a f***in criminal.
