header to mid pipe bolt size

[donkey_punch]

i have to pull my headers off,

and was hoping someone knows off hand what size is the hardware that holds the headers to mid pipe?

Thanks

close, they are 19mm, i just finish pulling the headers off

and for anyone who hasn't done it before and plans on to. you'll need a 19mm in a deep socket too.
