These are cat butts. I didn't do any ECU setup, just installed! My bike is EFI so I was afraid of misfiring but it purrs. The new mufflers don't have threaded holes like the original ones I removed so I just turned the bolt upside down and no worries. I did not buy new mounts. They are LOUD but moderately loud. My stereo still sounds great which was another concern and they cost a third of what the big brand claims. Excellent construction, premium chrome. So easy to install, a caveman could do it.
