The BW x-pipe is tricky to get a perfect leak-free setup. If you want perfect leak-free, I'd cut the flanges and weld them all.
Noted, didn't even think about the BW pipe leaking, why is it difficult on that specifically?

Was also looking at ESS and Evolve's already HFC setup, $1,800 and $2,650 respectively and that's just too much for what I'm looking for. Even though the BW with HFC's separate could end up being closet o $1,800 when said and done.
