part interchangable between zzr1200 and zzr1100

Hey all.
I've been reading about some parts being interchable between the zzr 1200 to the 1100 is this right?

Also if so do they need to be modified or are they strait bolt on replacements? parts mainly in question are the exhaust headers and frount indicators.

The headers and the front indicators are both a straight swap.

Cheers thanks for clearing that up for me
