I thought it would be helpful to post a comparison clip of the new version 2 of the AA EQ midpipe. This new version adds 2 more resonators to the system. (4 total for me) I loved my previous setup, but it had a super annoying tinny rattle rasp sound at 2k rpm that drove me crazy. With V2 it's totally gone which is fantastic. It does come at a cost, the overall volume of the system is lower for better or worse. maybe 10% quieter. My setup: -stage 2 -Catless downpipes -Active Autowerke equal length midpipe V2 resonated -resonated rear midpipe -DINAN rear muffler deleted burbles
