On the mes 30 1st gen, those who did the mailbox mod,
What size duct did you use where the chip loader is?
Did you remove the chip tray or heat shield?
Those that also put a stack on top, what size duct did you use and did you remove the entire exhaust opening or just the top adjuster with screw.
I think its all 3 inch vent tube but just making sure, thank you in advance
