lol, not to mod the fuel filter, i do not think she has ever replaced it, so i would like to have that taken care of, when i say modding i mean, intake, y-pipe and or x-pipe, b-pipes, cams, or perhaps even forced induction.
on another note i went to my friendly/ handy dandy discount auto parts and found out that the ls has 2 catalytic converters, 1 pre-cat and 4 mufflers, all ic an say in regard to that information is that car is massively restricted on the exhaust side.
