I used to have the kazuma on my 01 gts and it is mind blowing loud. no sound clip could ever show you just how loud it is. But put it this way, I got pulled over at idle one time because it is so loud. And it doesnt sound like a pissed off bumble bee, it sounds almost like an f1 car. it really is amazing. the only problem is that there is not silencer and i got stopped 4 times for it. never got a ticket but thats how loud it is.
