Also to note, my mechanic gushed over the quality of the part and the welds, going so far as to say, "These look so good it's ashame we have to put them under the car."

I got for a tune on the 11th, so look forward to one or two more videos. If anyone is interested in more or different views because they're considering these HFCs, let me know and I'll record something.
