Downpipe and flange

[NPloysa]

Going to ask this question again though I have asked it before!



Why this is so confusing to me, I will never know.



If I go with a 4" downpipe with a 5" exhaust system, the downpipe flange will fit my HX-35 turbine housing exit, correct?



And when I upgrade turbos, I will need a HX-40 style downpipe if I go into that type of turbo, i. e: HTB2, HX-40, B-1, etc.



Thanks for clearing it up!

All except the B-1. I think they have a different kind of flange.
