Initial review of the Motordyne Resonated XYZ. Totally worth it! I would say that I am 80% happy with the results.

The nasty sound on decel is gone, rather than a raspy can of bees, its a nice hum. Want it loud? Floor it, the exhaust still screams at full tilt. It's no longer obnoxious when driving calmly. The SRM blips don't shake the earth like they used to. I say 80% because that's a good estimation about how much it has cleaned up the sound. It can still get raspy above 4K, when driving with spirit.

I still haven't heard it from a cold start, another pain point with the Tomei setup, but I have high hopes. I'm also looking forward to see how the sound will change after a few heat cycles, once the resonator adjusts.

EDIT: I should add that there were no fitment issues connecting to the FI LTHs and the Y-Back section of the Tomei. Also, the 2.5" gaskets included with the Tomei are crap. It was my intention to reuse them, but they crumbled as soon as I removed the bolts. The 3" gasket held up fine.
