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?

I have the same cheap eBay Chinese muffler with secondary cat delete test pipes on my 2002 Boxster. No drone what so ever. Sounds really nice. I guess I got lucky. I also have a Fabspeed spec muffler exhaust with resonators. It drones like you would not believe.
