What do you get when you have 2 bung holes and 2 bung hole plugs? Completed dual carb /6 exhaust pipes. Now I can run an O2 sensor in each to adjust each carb independently. I also bought some thermal coating that was not cheap but no where near the cost of ceramic coating. I will see how this holds up.... Coated the inside of the Durtras as well. Went with the bronze so give it some clash with the dark turquoise.... Time for finally assembly next weekend!
