I wanted the cleanest looking as well as easiest to install catch can option for the low compression side as possible this is what I came up with.

AN10 hoses and fittings worked perfectly for sizing to work with existing fittings.
BOM
5' AN 10 braided fuel hose
90 degree an10 connector
straight an10 connector
AN10 hose fittings x 2 to catch can
hose clamps
3d printed mount
connectors to catch can
total cost minus catch can - @$40 for parts
1. use a heat gun to remove the fitting's from the plastic egr hose- just heat gently until it twists out from each end. you can reinstall also if you want to revert to factory
2. take 46" of an10 braided nylon hose and connect to 90 degree fitting from front of engine
3 take remaining hose and connect to other fitting (Back of engine)
4. Drill through cabin air intake using a 7/8 drill bit. (Tape may help with insulation)
5. 3d print a carbon fiber mount for the catch can
route hoses and use the AN10 fittings tighten everything up and bob's your uncle. (He really is my uncle)

 

Nice, please report back if you really catch anything...

 

Did both sides
