it starts from the 2nd cat.
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?
