Ferrari Mailing List: Re: 355 exhaust manifolds or thoughts on buying one...

[John Spangler (jspangler]

I think there are several outfits currently making replacements in
stainless.  One is in Connecticut and another in Ca.  I think one is a
sponsor on Fchat.  Replacing the stock headers with the same pieces is
stupid.  With the flawed design, they WILL fail again.

Why hasn't anyone fabbed up a pair out of stainless? Are these an
accurate
picture of the headers?

It looks like a 4 yr old made them.
