Do they rust alot or they are pretty good . I'm in Ontario canada

 

I haven't seen any with rust yet, mins at 190k and I live in Minnesota and haven't had any rust at all. Just get the car washed regularly in the winter

 

AWD mid pipes do rust out if you do not remove the tin heat shield wrapping on them. Inside of that is fiberglass type matting that absorbs water and slowly rots the pipe.

Another thing to look after is the rear brakes floating pins tend to seize if you do not put grease inside of them.
