Questions

[phiberglass]

I know a little about these but i would like to know more. what exactly do these things do:

exhaust, headers, intake, injectors, superchargers, software, and pulleys.

and what does "clears all around" mean?

for most of those things visit www.howstuffworks.com

Clears all around means swapping ugly red/orange tails for ones that are red/clear and then putting clear corners up front.
