I guess you could buy like 20”+ inch long resonators, but that would just be adding extra weight, while you could buy louvered glasspacks that are as long or shorter, and they do more of a job to quiet the volume, and also kill rasp and drone. Metal chambered mufflers like Flowmaster will do more if they’re a full size muffler; but single chambered smaller mufflers like the Super 10, will make your exhaust drone and be raspy, especially with a cat delete or long tubes.

The x-pipe muffler like the one Magnaflow offers, is also a good alternative. That’s pretty much what MBRP and some other companies did with a mid muffler, although they basically left the rest of the axleback as a muffler delete or with straight-through “mufflers” that barely do much. I used to have a Solo Mach X catback exhaust system, which is pretty much what I mentioned; with it having a full-sized mid muffler (not sure of the internal design), and muffler deletes with j-pipes on the axleback section.

I currently have a Borla Touring catback, which pretty much comprises of “full-sized” rear mufflers, which are fiberglass packed and are a straight-through design. The mid pipes that come with it, are pretty much non-resonated, with a single x-pipe. It does a fair job of quieting down volume, drone, and rasp. I don’t see the need for a mid muffler if I had a full axleback like this, but I could see myself adding maybe some smaller resonators, to kill the rasp and smooth the overall tone if I’m running long tube headers or cat deletes.

Thanks! Do you think switching to the touring axle back would help? Idk if it's the mufflers or the x pipes in the atak that make it so loud or what
