A friend recommended getting aftermarket blow-valves for my DINAN Stage 2 F07 550i GT so I could hear the turbos more. I already have a muffler delete w/ quad tips and straight pipe, which you can hear on YouTube:


Love the backfire and noise... but wouldn't mind the sound of turbos either. Im looking at these... http://www.tunersdepot.com/Performan...lve-20522.html

Are there any problems with bigger blow valves? I've heard that sometimes the engine blows out.. is it true? The Greddy Blow-Valve says it can handle 400-800 hp, mine is 520 anyways
