400 is way too much for that exhaust. you can see it already has rust on it. i would go with a full stainless catback because the snow and salt is going to eat that exhaust alive in canada. i have an apexi and the pipe that goes into the muffler isnt stainless, and the rust has eaten a hole in the muffler piping. if you live in a place that gets a lot of snow, and therefore the town throws salt and sand on the road, i recommend a full stainless exhaust.
