Hi guys, I want to ask some questions especially for you who are live in Canada or has experienced crossed the border using your own car and imported it. Please help me, because I am going to land in a few weeks and use it as a list of goods for accompanying. 1. Would it be a problem in Canada using dark tint windows? Is there any specific/limit how dark is permitted? 2. I have SUV Tahoe 2004and it has muffler/2 tail pipe, originally from manufacture has only 1 exhaust. How far modification on the car is allowed for RIV? Any suggestions are really appreciate it.
