what do you think backpressuring means exactly? just so you know backpressuring isn't a real term...

you get a certain amount of back pressure in your exhaust system. you can set up a pressure sensor before and after your cat. this will tell you how much back pressure you are getting in your header out of your exhaust ports and how much back pressure you are getting in your exhaust system.
