I measured 1 1/4 inch diameter on my standard tailpipe

1.25 Inch(s) = 31.75 Millimetre(s)

but I think that the main pipe work is much wider

anyone?

Can't you just measure it from your car? I mean, measure it from the outside and suppose it's a few mm thick, then you have a good idea what you need to make.
