5Zigen do make a cat back exhaust for DC2.....does your modified...because there is not much gain from an exhaust unless you are pretty deep in the modifying process....although if it the sound you looking for for now...and so when you do go further in the mod process (cams etc etc)....then a 2.5" piping would be beneficial to your needs!
what i would recommend is the purchase the muffler and get custom N1 style piping exhaust!....and get a HF CAT!
cheers!
