I don't have the latest model sportbike, but I love my bike and I know exactly what modifications I want to do to it. Bit by bit, I've been converting my Kawasaki 500 into a Streetfighter style bike. Because of my job I commute almost all over California, so I want to enjoy my ride.
I looked into may exhausts, because in all honesty, I simply could not stand the stock exhaust from Kawasaki. I came across Coffman's site, saw their YouTube reviews, and debated with myself for a few weeks.
I finally decide to place the order, as my own birthday present. I place the order, they contact me for follow up paperwork, and the exhausts ship the same day. Unfortunately, in all my excitement, I ordered the wrong color. I followed up with Pam who assured me it would not be a problem to exchange them. Which as it turns out, it was not. Pam was very nice, sweet, and attentive, and the same day they received by incorrectly-placed order they shipped out the replacement set of exhausts.
I don't have the latest model bike, but I am very pleased with the sound, look, quality, and feel of the ride. I will say my RPM have changed and function higher to output of torque, but that is expected since I now have less than half exhaust channel for escape pressure.
But again, very happy with the company and I'm very happy with the system. read more
