Great Sound!

Love the sound of this exhaust. Not too raspy, not too loud, but adds the volume that the engine needs. Also, along with this kit I recommend buying an OEM donut gasket to replace the original. My WRX is a Minnesota rescue, that gasket was toast after removing the stock exhaust and this kit doesn't include a replacement.

Ryan,
