I will be tuning my car on e85 here in the next few weeks.
My question is, will e85 and highflow cats be a problem? I searched and there was little to no info on it. I'm assuming it won't be, but I always like to get knowledgable opinions! I just don't want to be "blowing out the cat"

Not a problem,

The cats are just honeycomb ceramic that get hot by the exhaust flowing through them (heat transfer), and as any unburnt fuel flows in the exhaust gases through (even E85) the Hot honey combs , then heat of the combs helps to burn the unburnt fuel.






So fuels are not the problem with catalytic converter since they burn clean in themselves, but oil that is burnt and pushed through them instead to foul and clog the comb passages instead.
