A) the Spiral Flows were something I ran before I had long tubes. I knew it was going to be too loud that way when I put the long tubes on, so I changed it.
B) Right before I put long tubes on, I blew out the welds in one of the mufflers, so I bought a set of street series Magnaflows. To your question, I put the Magnaflows on the car while still having the Spiral Flows on...this was my attempt to quiet down the rattling noise from the muffler. I literally could not hear the car idle. It was so flipping quiet, I thought I had a Prius.
C) I run Dynatech long tubes, o/r x pipe, no resonators with Ford Racing AB's now and I absolutely love it. Not too loud, but not too quiet.
Derek, just go cut off the resonators. It's not going to be too loud.
For the record, guys typically don't go buy x pipes just because they're too loud. They buy them because of the flow characteristics at higher RPM's.
