I just finished installing my test pipe, much better than having a catalitic converter. by the way, it weighs like 25 ****in lbs., no joke, that thing is so caked up with exhaust powder its not even funny. it doesn't SOUND much louder than before either, now all i need is DC Sports 4-2-1 Headers, and OBX exhaust..and then my exhaust mods will be done...
