Exhaust Bung / Plug size ?

[nellyboyo]

I`m away at work at the moment so I was looking for a bit of help as I can`t measure what I want .
What size of exhaust bung or plug will fit an NK end pipe roughly ?.
I've made a leakdown kit but can`t find anything tidy to bung the exhaust up with .
Theres MX type ones about but I`m not sure i they are any good for it

Cheers in advance

I don't think it will work as air would escape from the slip manifold. It's better to remove the exhaust and use an expanding plumbers bung.

I have got one of those slip joint rubbers fitted. and thats pretty tight. I've tested it without the pipe on with a homemade blank and gasket on the exhaust flange , I just wanted to try it with the pipe on then when I get back .
