No resonator size just effects sound levels not power. Another question I'm sure has been covered but I forgot the answer or fix? Is it normal that when I let off gas at the end of the exhaust note there's a hiss like a BOV. I've somewhat checked for leaks and couldn't locate any and my check engine light hasn't come on. I have the HFC and 18" cf cbe combo. It has gotten a little more noticeable as my exhaust became broken in and sound level reduced? Is something wrong here?

nothing is wrong thats just how this car sounds. the second you switch out the stock cats you get the hissing on decel. No worries nothing is wrong.
