At random order I plan to do a few first mods before the winter begins. I plan to install ( Catback, lid, air filter, LCA, STB, SFC). Then next spring I can install some power. Any suggestions on what would be the best order? The car is 2001 Camaro SS.

 

if you would rather improve the handling and feel on the road, to get a better feel for the car before you boost the power, i would suggest sfc, stb then lca

and for power mods, lid and filter (typically done at same time), catback or cutout.

is it an auto or a 6spd? if it's a 6spd...look into a shifter or at least a lou's short stick, it will make you a much more proficient shifter.
