what exactly is backpressure and why is it bad?

what is a race and mid pipe? is it between our header and our exhaust?

i've seen some decent gains with headers, race and mid pipes, exhaust, intake, and S-afc ii (tuned) and it seems I will be going this route unless I get a daily driver then its all boost all the time!

Thanks in advance for your help.
