Got some time riding with the db killer. Makes a huge difference in sound. With db killer in, it is louder than stock but not by that much. Much quieter than without it in, quite noticeable difference. Highly recommend you buy one if you get this exhaust, unless your goal is a super loud bike. Performance felt very similar, would still like dyno runs with and without it in. Talked to Toce the other day and they said they were getting a cbr1000rr in the shop next week. He told me he could do runs with and without the db killer in, as well as some decibel measurements. Hopefully I hear back on that!
