Yes Adrian that's right,
Thing to remember is that Mk2, E1,E2, and stuff after all had footrest hangers and I found by trying to fit to my Z1R,78, on my E2, it sat behind the footrest bracket, so it looks like the 4into1 straight pipe delkevic for me, I tried swopping stuff around, and have come to the conclusion that it don't fit correctly, I first mounted it inside the rear foot rest bracket, looks really good, but fouls the swing arm, so relocated, when all tightened touches the oilfilter housing bolt and number one and two are tight against each other so just not right, this ain't no black lettered harris its a modern piece built to a cost, its brand new, never been outside on a bike, so the marving which came with my 1R, i'll probably sell and the harris can go back on old 1075shaftie, and i'll invest in the straight pipe version as it weighs diddlysquat, and 5 years warranty
