are O/R H pipes legal or illegal? will they pass emissions test if they are on the vehicle 2002 GT. Does the 2002 Stock GT come with a Catalytic converter if not what is the best one to get with flowmasters and O/R H pipes? I want the bitch to sound mean. Will i notice a difference in sound when i add headers, cams cold air intake etc... and will you fell the power immediatly.

o/r means offroad, meaning meant for off the streets period, they are all illegal. But 75% of people use them anyway, as long as you have somewhere to get it inspected. Cold air intake is worthless and will not notice any difference, cams are a good way to gain some extra power and sound, long tubes will also make more power from what i hear they are a pretty big gain in 4.6 motors and sound alot deeper.
