Had another poke around this evening, lokos like my pipe actually has multipe small holes, see image - I've stuffed the pipe with blue paper towels, you can see the blue through the holes.

I've got the right allen key bit for the two bolts, but I cannot work out at all how I am going to get to back of the pipe - I could see from beneath with a torch, but could not get hand to it, and can't see it at all from the top.

Am hoping when I remove the air intake in 2nd image that a) I'll get better access to the 2nd bolt holding the pipe on and b) it might help me see the back of the pipe from above.

Any tips / advice please?
