Using "J pipes" to remove drone

[falcon_bandit]

I dropped the twin rear mufflers on my aurion to see how it sounded, and surprisingly these engines sound quite nice, and a perfect loudness. Was happy to get straight pipes made up in there place, until I realized there was a sonic boom at roughly 2300rpm under load which is pretty deafening.

At first was thinking couple large resonators but am worried will kill the sound too much. So then maybe a couple hotdogs, but worried they won't do anything. Came across the j pipe theory of removing drone & want to do a combo of hotdogs & jpipes but I'm a bit confused how to work out the correct specs for the jpipes. Can anyone help?
