a muppet is you. its just like calling you a tool, or a moron etc, except, i use muppet.
so erm, if i gut me cat, and put a k&n in my EF, i should have 210kw, sweet! think i might go and do that now. oh wait, its got a K&N and a full exhaust system and cam, and that costs a LOT more than your simple mods to produce those figures. ur mod = $100. my mods = $2000...
damn if you had of been around before i spent that 2k, i would of saved a packet!
FYI the ea was pushing approx 120kw from factory, with what mods do you think you'll gain an extra 60kws?
