Big Block muffler choice

If I remember correct I’m running Dynomax ultra flow 17233. Before I put tail pipes on, it would shake everything around. I’m running 3” with x pipe all the way out on my big block Demon. Fairly docile at idle, but when you squeeze the skinny pedal it opens up. I will say interior noise isn’t exactly quiet even with sound deadening, but very tolerable to me. The tail pipes made a ton of difference.
