i just put a megan racing downpipe in my tt and it sounds great. the rest of the exhaust is stock.it was a front precat eliminator and main cat eliminator. its totally silent if i dont get on boost and above about 2.5k rpm but once you get on it, its wicked loud. if you go by cars or on a bridge its crazy loud.i raced a truck with a built v8 in it and my friend could hear my car over the the truck with the v8. my car doesnt have a ricey sound its deep and LOUD!!!
