Long story short, I had the exhaust for final testing, there was a bit of fitment issue with the hangars and a bit of drone. Riss then took the exhaust off, and redesigned their muffler and pipes section to work on eliminating the drone, and worked on fixing the hangars issue. That's why there has been a few delays. Should be out soon?
