hey hey. . i know i can just look in the manual. . but then i want to know how much gas is in a full tank EX 2k1 civic. . and if you add like a dc sport header, full cat and exahust, and intake. . .which means all the air flow of the car. . does it increase ur mpg?? Ohhs. . for those who do have those kinds of mods. . meaning you have the intake and exahust with cat, does your rpm and mph slow down quicker when you just let go of the gass when yoru doing like 45 or something??? cuz mine slows down faster than before. . . soo yeah. .thanks ya'll!

50 liter gas tank. I think that's like 22 gallons, not sure.
