Modify an aftermarket muffler?

[ecp]

I’ve been poking around with different mufflers and can’t seem to be pleased with any combo I try. I’ve tried two modded stock mufflers (like the fister) but it just sounded like a raspy fart can. I have a circuit werks v2 muffler and it’s been my favorite, except for the drone. I was looking at the fab speed muffler and the 987 muffler and they seem to have a pipe connecting the two separate mufflers.

The v2 is basically the same as the other twin can aftermarket designs but has an x pipe before the tips. I was wondering if anyone has ever actually attempted to do this. I’ve seen people talk about it but never heard of anyone actually doing it or any results. There is also enough space to where I could put a resonator connecting the two.

Any input would be appreciated.
