Hi DSB,
Try this link on another site for photos of resonator and backbox internals. My Cats are still on.

Wallance - The resonator is the rectangular'ish box mid postion underneath , after the 2 cats. This can be replaced with either straight, H or X pipe designs. I have removed mine as the resonator design was a simple two straight pipe i.e no crossover, so little issues to worry about. I haven't removed the Cats as i was worried about backpressure and emissions testing..
The car is louder, and has run fine for 4K miles, and has been checked by Merc recently with no issues.
Upto you on whether its right or wrong for yourself
