i putting a b18 into my civic soon and i think im getting the hayame cat back exhaust cause i love the deep sound and the nice power gain, about 20 hp from the last civic i had with a b18 swap, but that car had stock header. I was reading on which ones will fit with a b18 swap that is keeping ac and power steering but they did not specify if that would allow for those things, anyone know which ones will work, and make some power?? i haven't desides on if i want a 4-2-1 or a 4-1 yet so either. thanks ahead of time

this ones says that it works with ac and power steering but i have read offroad only about this header cause theres is no room for the cat, it that true, if so could it be easy to move the cat down the pipe more and shorten the exhaust a little. thanks
