Relatively easy to install. The second sensor (underneath) was not so fun to deal with. Remembering not to tighten everything until all pipes are aligned just right, the install went well. Replaced the hangers as well. TIGHT & CLEAN fit. Forgot to wear eye protection - will never do that again :o) Butt dyno indicates more power on tap, and keeps it without peaking as soon as the OEM version. Sound is a bit louder, and to my liking. Only downfall is that I can't show off the craftsmanship. A must-have to establish a firm foundation for future tunes.
