It depends. Without the testpipe it is pretty quiet. It has a real low deep sound. With the testpipe it sonds like a drag car. I felt power all through the band, especialy with the testpipe. I can send you a picture but you will have to have high speed interenet. I am a photographer and the smallest size my camera will do is 3000 k. If so just pm me your address. I can also send you a pic from the company if you just want to see what it looks like.
