Well I installed them this afternoon, pretty straightforward, took about hour and a half. Stock weigh 21 pounds and the Cobras weigh 30 pounds. Nice sound, will have to ride awhile to be sure about the drone. Excellent engineering and configuration. They look really sharp from the back. Chroming could have been a little better, I have one pipe that has some distortion in the chrome when seen from certain angles. Not worth the postage to send back. The fit into the heat shield was excellent. Make sure you don't lose the rubber gromets off your old muffler you will need these for the Cobras. Wing Stuff was great to do buisness with and now it's time to pickout a seat.[Hurry up Ultimate that Corbin is really tempting me]
