Muffler delete will definitely increase noise levels but the resonated X pipe makes it perfect.
What you could do is replace your stock resonators with aftermarket like vibrant and add an X pipe. This should help a ton. The stock resonators suck

Unfortunately my resonators aren't side-by-side, so I'd have to get additional tubing cut to do so. I've thought about adding a resonated x-pipe instead of just the plain x-pipe that I'd planned on installing. What Magnaflow muffler model # is that? I'm ordering a muffler for my other truck as well, so maybe I can combine shipping with the seller and save some money.

Magnaflow 11386 Stainless Steel 2.5" Oval Muffler - you could always go with a custom x pipe and resonators separately.
