Hi Guys i`m very new to this . I have just bought a 2000 MY01 impreza wrx turbo with a muffler (for noise). Just wondering what or if there is anything i should do to this car as it is apparently stock & i know stuff all about cars ?? I have looked on you tube & there were some things on there like sway bars etc , turbo etc. Was looking at a Cold air intake , would that be of any value ? & should i get someone to check it out if it has the stock cat converter ( saw on you tube they are Shit ).............Any help would be appreciated. P.S. i have a top mount intercooler.( if that helps)???
