Headers with hollowed cats and cherry bombs?

Anyone have a setup like this on their van? I'm wondering if this is going to be too loud. My buddy had an Aspen with a slant-6, no cat and a cherry bomb and you could bearly hear it run. I imagine the V-8s to make more noise, but I'd like a ballpark on how much noise, and how often to expect exhaust tickets.....

Thanks,

Jay

no worse than those bloody honda's, and i can respect yours
