if you are worried about the smog, just get a louder exhaust than the Akra and keep the stock X-pipe. The Akra needs a catless X-pipe to shine its best in my opinion. Get a Challenge catless race X-pipe and a tune then when smog check time comes have your oem X-pipe reinstalled. Yes it is going to cost more in the end but you get the better setup that way.
