Hey jet how much for 2.5 couplers? If you look at blageo23's engine bay, [hope you dont mind me useing your pic as a reference] i have the red coupler right before the elbow down to the smic. Would i need a reducer? Or just 2 2.5" couplers [one for the smic connection, and one for the tb connection]?
