most recommended exhaust? it's totally up to you. though you don't have many choices at the moment. the magnus turboback (it's only from the casted part back) and the jic magic catback are your only viable exhausts currently. it's either that or get a universal muffler and get custom piping. if you wait, ion performance and spool turbo will have exhausts out soon. greddy is supposed to be designing an evo exhaust for our car. magnaflow is developing one as well. just wait a while...me i plan to go custom 3" piping with an hks hi-power.
