Aiball...from your pictures, it doesn't seem like the resonator would affect the exhaust at all, but maybe reduce the volume but not by much.

Hmmm more to think of now...

abs...I'm ordering it soon but wait for the Invidia to manufacture the AUDM model of the dumpipe, so like 4-5 weeks away from it arriving.
Also assuming your Invidia catback is the resonated version? and not the racing version...
I may just get the resonated one too now as it doesn't look like it would affect it much....just wonder if it does kill the race engine sound - have a look on youtube, the non resonated version sounds soooo nice!

Will let you know what its like
