The only one I could see being any competition to the KillerB is the Invidia big tube race, any expirience with that header? KillerB still seem superior in design to that? Thanks for your input.
The use of 321 stainless steel of the Killer B header alone makes them better than other headers that (may) supply similar results. I have not seen any information on the Invidia big tube header though...
