Boss on headers is for Lambda probe - M18x1.5 - Engine core plug fits nicely.
Boss on uppipe is for EGT probe - M12x1.25 - Cut down a M12 fine bolt.

Darren I used a Toyota sump bung in the Helix up pipe, TSL can supply a lambda probe bung but you might be able to get 1 from a local exhaust stockist cheaper, someone like Southern Exhausts.
