Ducati Bevel Single Finned Exhaust Manifold Kit 250 350 450

To suit nearly ALL Ducati OHC singles of the sixties, to my knowledge.  Includes special stainless nut and clamp-on aluminum finned collar, fitted as shown in 2nd photo.  Absolutely beautiful and functional, this kit aids cooling at the exhaust port where it's needed most and also acts as an indicator of exhaust nut tightness.  Mostly though, it looks bloody bitchin'.

(Note:  Two exhaust gaskets likely required.)
