This may sound stupid to some but I wants what I wants I'm getting my 2.0TFSI Quattro re-mapped to increase it up to the 250bhp+ mark, but there is one thing I really want to add to the car. It's not so much a performance upgrade as I just love the sound of a loud blow off valve. Would it be worth/is it possible to just stick a loud blow off valve in, or would it not produce the sound I'm after without some other form of upgrade? If it is possible, any recommendations on which one to get? Thanks, Stefan.
