4 in 1 Exhaust modification

The EMPI Exhaust I bought lately had the support for the original setup. Having twin carbs on my new engine I didn't need them so I decided to modify the exhaust.
This is what is left after removing the pipe.
Good opportunity to use my clarke welder for the first time. I will try to fill the hole.
This is me in action.
Ok , it's a bit messy but not too bad for a beginner.

And this is how it looks after a bit of grinding
Hole nb 2.
Not as messy as the first one.
Job done.
