mate my ute does the same with a new fitted APS exhaust, just like yours, there is a klunking when you shake the talipipe sideways... or drive around RH bumpy corners....I was going to load up the rubber hanging bush a tad sideways to eliminate it, but it is only every now and then - and I kind of live with the odd clunk now ( mine only bangs if you shake it sideways) if it banged all the time, I would have gotten creative, but I was lucky its only now and then. my ute is stock standard height etc cheers
