Who the heck cares if it hisses!! Mine hisses away! It bothered me for about 2 seconds after my test pipe install but once I felt the dif in power I coulda cared less. I could personally care less about it at this point. If it adds power its all good in my book. Sh!t if blasting opera music made may car faster people would hear me blaring Pavoratti at 100mph!
