Found this while surfing the web, seems like an excellent source of information for anyone who wants to know more about exhaust system upgrades. It details how to measure back pressure and its influence in choosing the right sized exhaust piping to upgrade to. Also has some stuff on high-flow catalytic converters and resonators.

There are numerous pictures and diagrams as well.
