Wouldn't a US conversion put a cat on it anyway?

Has to be something more than cat or no cat

Again as I said its maybe the head but for sure cams.

Have to find the engine #

I would suppose I have a have a cat...

There is another cylider under the car...I thought that had to be the cat

My exhaust is sort of dual parallel
its seperate pipes running together
2 pipes going into muffler
two out

exhaust manifolds are sort of header design w each one on a exhaust port less back pressure than the amorphous US stock manifolds.

Hard to explain but lil better than the av US car...
Well its a Benz..

My bird is jealous
I;m sending more time on the car...
but I want to get to know it so I can become comfortable with it.

Since it really is a 305ci
it shouldn;t be as bad a gas lush as I thought.


well better go...

have a great day
