What the heck...2 catilitic converters? How is THAT engineered? R they 'inline'? (See my sig., it's all learning to me). Must make for a Really Clean exhaust(?). I had alfas in the 60's with a "resanator". Gets kinda crowded under there. But Y 2 cats? One for each side?
Then this 'intermediate' - like a short funnel or step up/expansion w/in couppla inches?

FORDSIX PERFORMANCE • View topic - Cheapest HP/$ for 4.9L? I asked the same question on another forum that specializes on the engine in question, and got a very different answer. With the right set of mods, you could pick up 30hp or so WITHOUT bumping the capacity of the injectors ...
