evan3037 Posted September 21, 2005 Share Posted September 21, 2005 if you take off the cats its illegal, the cats take all the polution out if you take them off you will get great flow but you wont pass inspection because of emissions controls Quote Link to comment Share on other sites More sharing options...
VenomGTO Posted November 10, 2005 Share Posted November 10, 2005 I don't know anything about Lexus, but how about an underdrive pulley and a handheld programmer? How are you guys doing with traction issues? I know new tires did wonders for launching my car. Quote Link to comment Share on other sites More sharing options...
