outlet and intake sizes

[Ds650rida]

can someone tell me what the sizes of the inlet and outlet for the stock twins on a 1j are and the size of the intake inlet?

And also if anyone could share with me their routing and setups for intercooler piping that would be useful as well

Thanks.

2 1/4 and 2 3/4 respectively IIRC.

so roughly i would need a 3" coupler for the intake and a 2.5 for the pressure pipe?
