Yes i got hks super dragger2 on mine... I got done by epa and i managed to get away with fitting a hi flo cat (i know i know but anyways), a highflow middle muffler and removing the hot dog stlye thats comes standard in the system, my car tested by epa came in at 82.3dbs which is from what they said very good.. The shop i used liverpool exhuast said that the hot dog stlye muffler is only there to increase noise emitted so changing that worked on mine.. But still to the day some coppers dont believe me that it passed epa with the super dragger rear cannon as any1 who has seen them knows they are very large look good on the ass off a 33 i think..
