I have about 600 dollars right now and I'm thinking about getting the hks hypers on my 300zxtt. I hear a civic fly by and hear that raspiness and thats the last thing that I want on my car. Does anyone know if this is a raspy exhaust system. I know the looks arent perfect. I'd also like to hear maybe a couple sound clips or something or videos if anyones got them on a 300zxtt. I've found about 2 but they diddn't really show the sound off very good.
