If emmision testing is a concern, the cats need to be installed for testing and keep a light throttle, then removed till next testing time. Every hi-flow cat manufacturer's excuse has been "poor tuning". Two high end cat manufacturers both reccomended this to me.

Well said;
I kind of gave up on responding to this same sorry excuse "bad tuning".
Too much finger pointing in the auto industry. Manufacturers / vendors need to take responsibility for their actions just like the consumer has to when shit screws up and it costs them money to resolve. When things go well everyone's ready to take credit, when they don't everyone starts pointing fingers.
Test and QA the CATS at varying power levels, it they don't hold up, just make different offereings for different requirements and charge accordingly giving shops and consumers different offerings. Some, will pay, some won't. Simple, honest approach to doing "
good" business.
