I purchased the triangle JISU cans. I'm very happy with them. They're not a whole lot louder than debaffled factory cans at idle or revving. But under a load, there is a noticeable difference. I don't have a video with a driveby. I really want to listen as someone else rides it by me, but haven't had a chance to yet.
2007 Honda 919.
Used to be Red, now it's Green. Open for name suggestions.
