SeeeeeYa- I'm very interested in your muffler mod (smart thinking) and the resonated midpipe, very little louder and better tone.
But I have ground clearance issues, something drags under my 2016 WRX unless I enter my driveway just so. After it warms up here I'll get under and check what's dragging. If it's the midpipe a larger one won't work for me. I tried to contact Nameless Performance to ask how much larger their midpipe is than stock but because of the holidays I couldn't get in contact.
