I know nothing about what high-flow ones will help do. I only know the purpose of a cat and a muffler.

Smaller stock engines don't see much advantage of aftermarket mufflers or cats. Bigger engines need more flow, so they see greater gains w/performance exhaust even when stock.
The biggest advantage of using high-flow exhaust systems is when the engine has been modified, and it now needs the extra flow.
Its all about backpressure and exhaust scavaging. The exhaust size and length is tuned to pull burned gasses most efficently from the engine. A tuned exhaust "scavages" the cylinder when the engine is in its powerband. Too large an exhaust will hurt low-speed performance, while too small will hurt top-end power. The proper size depends on the application.

yes they do. you just have to be aware of the legalities of installing those parts. in some jurisdictions the parts must have a CARB EO number for your vehicle to be legal to install. also on 96+ cars a high flow catalytic converter can set off a check engine light. there are 1 or 2 O2 sensors behind the catalytic coverters that moniter their efficiency. i have a 98 mustang with a K&N FIPK, Bassani Offroad X pipe and weld in mufflers. the mileage is about the same as stock, but i tend to keep the revs higher, and i tend to not care about how much gas costs. i also have O2 sensor simulators on the rear sensors to mimic the voltage variation that should be present with cats.

These would help for the exhaust but what comes out first has to go in. Improving the intake system first will be more noticeable.

Simply put...it lets the engine "breathe" easier under a heavy load, thus maintaining performance.

Maybe it's higher flow, as in exhaust flow. Could mean better performance.....

Under normal operation there would be little, if any, improvement.
However, If you drive a truck and pull heavy loads, and have your foot to the floor, there would be less restriction under hard acceleration.
