This is the turboback setup so it has a resonator. Which I would also suggest as 27won does because this is on the edge of making long trips miserable. But I did a 2hr drive to my autocross event with no issues.
It's much louder than stock but not over bearing. It's loud on install but settles a bit over 100-200miles. I put a clip of the interior noise cruising at 70mph. Music will easily wash out the noise on the highway. As for drone, it seems to have some when trying to accel/decel in low revs in 5th...
I got mine installed a few weeks ago now. Here is a few clips.
The first two are right after install, cold start and fuse for valve was pulled (so it's open) also sorry sister got confused by the manual when I was getting her to rev it.
The third clip is a short one from my autocross day.
Thank you so much, was searching all over for this part.
I also had a mishap when installing my lowering springs and I'm hoping its just the seal thats ripped. Been slowly leaking fluid on driver side.
