Default O.S. 140RX Header

Needing a new or replacement header for my O.S. 140 RX. Here is how the old one now looks!

Have you contacted Macs? I think they have this except it bolts directly to the engine.

The MAC Header is a 7/8" The OS is a 3/4" So you will need a different diameter of tuned pipe
