You removed the cats in the g56 pipes before install? You were not shipped a new ECU? Then that would be a Stage 1 with complete headpipes, mufflers and bobbins for mounting. If that correct?
The G56 exhaust did not have cats. So, I'm now catless - but there is no inspection or testing requirement here for motorcycles.

The CATs are embedded in the header pipes, not the replacement pipes, so unless you physically removed (with some difficulty in truth) them when you have the thing apart, you'll still have them in there blocking things up. Unless you need them for emissions (which they don't really help much anyway), then all they do is be a nuisance.
