I have a Toda Manifold but does changing a cat back exhaust from say Js to a Mugen require a remap? Need a new exhaust and would like the Mugen Twin loop but I’m not sure if doing such a thing requires a remap of the K-Pro, I know changing the Header would most likely require one but I’m not sure about just changing the exhaust.

Header yes, exhaust no. Unless you are one of those freaks that has to have the a/f and ignition just perfect..
word, unless it is some crazy 3" job on a boosted setup

Freak = Yes
a/f and ignition just perfect = Hell No.

Was thinking a remap of my existing K-Pro map is bit extreme but I don’t know enough to know for sure, think I will change it and run some data logs and see what happens

only for f/i setups and/or if you remove your cat-back and run header out. This will change your af ratio's but not require a full re-map
