Yes,
when I ordered the exhaust they asked me if i was using ram air or stock manifolds.
I ordered the concours kit which included all the metal hangers and clamps plated so they wont rust and the cast iron flanges that mate to the exhaust manifolds are Jethot coated too.
I got the exhaust manifolds Jethot coated on my own so hopefully the exahust system wont rust up like natural steel would.
