That exhaust on the brochure is not correct. The 1970 hard tails had the exact same exhaust that capgun cowboy posted. The 1971 hard tails used a black Taylor slant exhaust for left side rear exhaust. 1970 used straight intake with diaphragm carb but in 71 they changed to a slant intake with bowl carb so the brochure is wrong for the intake and carb too.
