Svt performance actually did a test on the 2011 gt and 19 horse is gained on the dyno by killing the cats.. I'm sorry the the best bang for the buck there is. Wait I just looked that's 19 with an X pipe the H pipe is 3 less.. still a bargain ... all I need is a take off set of gt500 mufflers.. someone can have my flow master axle back as trade!! Ha ha
