Hi mate no you shouldn't have to remove the rad but will need to remove wings bumpers lights all that sort of thing and cut into parts of the car for the pipe work and bumper for it all to fit. So if you're just wanting it for the look I wouldn't waste my time and money with it. But it's entirely your choice I won't discourage anyone from doing what they want to do to there car. And I'm not sure if you would loose the fogs I guess depends on the pipe work really. But I would say looking at others I have seen the fogs would have to go and be covered.
