Unless you are going to be increasing your airflow with something like a 64mm turbo, don't waste the money on anything over 4"s, unless looks is high up on your priority.
It's your money, but I also can't imagine that sharp upward angle being good for getting that exhaust out with stacks as well. As far as efficiency goes.
