I've thought about the same thing, had the non resonated with a catless downpipe, was way too loud, switched to a catted downpipe and didn't like the sound and finally switched to the part resonated and been happy with it. Always wondered if the middle resonator delete pipe with the front resonator would return some of that turbo spool and make it a littler louder.Have you tried replacing the center resonator and using a front resonator? The resonator looks smaller. I thought the unresonated was perfect until I got a catted downpipe, then it sounded farty. I installed the road+ resonator (center) and it was too quiet. I'm wondering if using the front resonator and removing the center resonator is the in between.
