how would one add a cross over pipe to reduce drone and would it even work?

add a small pipe connecting the two exhaust tips which is downstream from said muffler? or maybe a straight pipe connecting each muffler together?

If you’re going to add a crossover, I would think that upstream of the mufflers would be best.
