has anyone used one of these? I'm talking about the ones that look like an hks bov. Was thinking of switching for the hell of it so that I can sell my friend my turboxs rfl. Does anyone know if it sounds like the hks because I want the hks bov sound, but barely hardcore anymore to spend the money on the hks bov

 

you should be able to contact the manufacturer and they will have sample clips of their product in action.. i don't know anyone who runs one of those things.
