Flow is quite a bit better as well, as the stock muffler has a lot of baffles on the interior that may make it quiet, but don't do you many favors when it comes to performance. Despite the increase in flow, it's not a loud system. We always keep in mind that you have to live with your exhaust on a day to day basis, and it will not punish you in that regard. During steady speed driving on the freeway there is no drone - it's actually quite quiet.
But when you get into it, especially at lower revs, it's presence is certainly there. It's got a nice deep tone to it, a perfect complement to the character of the 08 STI. One unit has already been fitted here, and we'll soon have them in stock in America at an AVO distributor near you.
