After more research it appears that the nipples are for the crankcase breather tube and the EGR or PAIR valve.
I have seen online some people using small filters at the end of their tubes, so if I switched to a pod filter over the carb then I could feasibly put a small separate filter on the end of the breather tube, after it runs through a T-splitter, 1 way going to an oil filter and to a catch tube, the other going to the new small filter.
As for the EGR valve tube, I have seen filters with single nipples for a Tao Tao Hellcat that would be alright fit, and the airbox could be replaced with a Grom box if I needed to.
I have also read about people capping the EGR, I don't need it for emissions... Thoughts?
Anybody have experience with these systems?
