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.

yep the race pipe is between our header and exhuast....ive gone from 165.4ish to 199.9 with full exhuast intake and sfac2 tined out...and even if you go f/i go supercharged so you can keep your exhuast setup

what about the mid pipe? Does it go header->midpipe->race pipe->exhaust?

^^^
header - removes 2 catalytic converters
y-pipe - removes 3rd cat
b-pipe - straight pipe or resonator (varies on make)
exhaust - axle back (various shapes, sizes, angles, tips, etc)

so when people say they've removed their resonator....they've removed the bpipe?
