what performance exhaust are people running am tempted to run back box less but worried about the noise produced as I have heard a few saying it will be stupidly loud and sound like a tractor, others say the Turbo will silence it and it's fine and below legal limit? if someone that is running back box less or with a straight through like a cherry bomb could upload a video of it on YouTube so I can decide either way I would be most grateful.also on the gordini meet 2009 (YouTube) the silver gordini sounds nice is that a side exit? thank you
