[acura_ek1]

Ok Im thinking about buying a hiflow cat in conjunction with toda race headers...
but im not sure which one to buy that doesn't cause a permanent CEL
Any help will be appreciated...thanks!

Many people are running Metal Cat. Only one guy so far that reported here he got CEL.
Im running RT cat, with Toda header as well. It has to be cut to match though.
