I have a 93 Prelude that I am installing an FMax kit on. Well, I was just looking at the downpipe setup and I am not going to run a closed loop setup. First question I have, Running open, the dump tube curves back towards the block, any worries with this setup? Second question, can I just just the closed loop connection cut off the downpipe and welded? Any worries with that? Thanks for your help.
