Cat back exhaust system

I've recently found information indicating that a flowmaster cat back exhaust system implemented on an otherwise stock SC can give a considerable increase of BHP.. Obviously due to the significant backpressure found in the stock system. This leads me to the questions..

How much horsepower can be expected out of different brand catback systems on an otherwise mostly stock SC? Do any of them vary significantly?

Which systems have reputable durability with stainless steel construction..

and finally which will not increase engine-exhaust noise to police attracting levels?

As you can probably see, I am considering these questions for a future exhaust upgrade. I expect to keep a resonator as it seems to be the best way to maintain good sound without drone.

Thanks for your help..
