I ran probably 2500 miles with just pipes. I unplugged the o2 sensors and it ran just as good as stock pipes, performance wise. It did pop/back fire, so I had the performance down load added. Bike runs smoother, and no pops or back firing. Almost never. Just the occasional that occurs on any air cooled V twin.
