RE: I5 Tubular Headers

["Duff, Ian" <iduff@charter.com>]

We should start to refer to turbo or N/A on the I5's. My N/A 1990 Coupe
quattro has a Real Nice Factory Stock tubular stainless steel header.
Early Coupe quattros have them standard, 'round about 3.90 build date (I
think) the factory switched from tubular headers to cast manifolds. No
ideas about I5 turbo headers, though.
