Not without serious modification by an experienced fabricator. The manifolds certainly wouldn't match up if you're talking about the entire system, and you might as well just buy a slip-on or other exhaust solution. It just wouldn't be cost-effective unless you had a line on a customizer, in which case, why bother with aftermarket anything?

As for the handlebars, the JPags are just drag bars on risers, like a lot of the newer manufacturer-built "choppers". I haven't found the diameter yet, but they look to be 1" bars, which would not fit on the GZ risers, and would more than likely also need retooling to physically fit. Like softie said, you're better off just getting aftermarket 7/8" bars in the measurements you like.
