<span style='color:darkblue'></span>I know everyone on this site has different opinions about which exhaust to buy. There are a lot of different horsepower gains depending on what you go with. That's all good if your out racing. I know for myself the sound of the pipe has a lot of influence on my choice. So, i thought it would be cool to see the sound range of most of the exhausts available for a busa. I would like to hear it all, from slip-on to $2000 akra full systems. I will post my yosh system as soon as I find a mic. Let em roar!
