My prior experience with exhaust taught me that I always had a donut gasket at a joint like this. When I pulled the manifolds off neither pipe had one, and neither Oreilly's or Autozone can find a correct fitting one. Does this joint not get one?! Thanks in advance!!



Also does it look like these motor mounts need replacing?

 

I think the converters use a spherical end that seals just from bolt pressure at the flange.
