182 Exhaust Surround - Dimensions

[Darmon]

Hi guys,

does anyone know the size of the 182 surround?

I've just bought a powerflow exhaust, which is twin pipe, and i'm hoping I can use the 182 surround to go round the bumper cut out which will be needed to make it sit flush.

I'm not hopeful of it happening, but i'll do it if the sizes are right
