[Roadsters] exhaust manifold leak

[Spedlyy]

Paul,

I've been told that installing a short section of braided flex pipe (common 
on modern front wheel drive cars) just below the flange will help to relieve 
stress on the exhaust manifold collection point.  I've had the crack in my 
manifold braised, and I've replaced my motor mounts, but I haven't had the 
flex pipe installed yet.
