04 forester 2.5xt .. had failed donut gasket and have decided I'd like to just get a nice new exhaust lol. Thinking of getting a custom turbo back built, unsure whether to replace cats with sport ones, decat, or stock cats. Does anyone run sport cats or decat exhausts and have any issues with mot? Will it need remapped? Car is stock
