I just installed my Borla touring system that was on my 2019 AT4. After contacting Borla I was able to confirm the exhaust is the same except for the tailpipes. I bought the tailpipes from Borla and as you can see they are very similar to the stock rear exit exhausts. Probably could of modified them to work.
Side note, I was thinking of going to the S type as on the AT4 this touring exhaust was very quiet and could barely be heard. On the Zr2 with the pipes pointing down the sound is a lot more pronounced and I'm glad I didn't order the louder system.
