Hi Guys, I found a seller in ebay who sells Apexi cat back systems for a wrx 2009 4door sedan. the price is around $800 including postage. Just want to get a feed back about the system if somebody already got it in your car.

I am looking for some performance as well as more sound from it. Any feedback will be greatly appreciated.

Don

You won't really get any performance gains from a cat back. You will want a turbo back + tune if you want power gains. If you just want rumble, get a diff-back done.

Check out one of the forum sponsors Ultrex for exhaust options also.

As Trolley has stated, just get a diff back if you want the noise.
Should cost you under $400 to do and will be an improvement over stock.
