you can put any muffler that will fit under there. any muffler shop can help. they don't make catback systems for your car. it was built to be a luxury car, not a hot rod. all a muffler will do is change sound. on that vehicle you won't get any performance benefit.


unless its a GS. Then it IS a performance car, and with the blower an exhaust will help exponentially.
