Hey bud, did you install your wideband O2 sensor yet? If you haven't, another option for you instead of using the 12mm to 18mm adapter is you can tap the stock bung to 18mm. Use a 16.5 mm drill bit & 18mm tap. There's tons of cheap mid pipes on ebay now.Finished getting all of the Woolich parts installed, wired & soldered up & tucked in nice & neat. I haven't entered the header diameter & length into the WRT software yet but ordered a take-off stock exhaust off ebay that is schedulaed for delivery this Thursday. It was only $75 and is in great condition, off a 2018 600 (wrecked I suppose) but has no dings or rust. Even has the O2 sensor & exhaust valve still installed. Looks like some dirt on the cat, could be light rust, but the cat will be removed anyway when I have the 18mm O2 bung welded in place of the stock 12mm and add a mid-pipe & M4 exhaust. I'll eventually go with a full exhaust but this one is just for practice with tuning a modified exhaust. Eventually want to look at a Yoshimura or Akrapovic.

I think the wrt tuning gear is the best out there now. I wish I had known about it before I got my tuning gear.
