So let's talk about what's working for headers on inline conversions.

ABA. x-flow head. 50 degree.

Stock twin downpipe manifold doesn't foul motor mount but it's
uncomfortably close. So besides Don Hanson (who's sent me a ton of
pictures), who's had some success in building an exhaust system that
didn't require frequent crack repair?

Suggestion has been made that there might be a suitable single pipe
manifold. Fox? By my calc's we need about a 2.25" dia pipe to equal
the flow of the twin.

Muffler is going to be mounted as diesel-vanagon.

Pointer toward pictures would be outstanding!

Alistair, do you have pics of Frank G's system?

As always,

Thanks in advance

Jim
