is there a way to dummy a 02 sensor on a ram 2k3 4.7.i want a deep sounding growl but i dont want to shoot my gas miliege into the gutter. i have run the truck straight pipe from the cat and my i say mi insides still hurt and im partially deaf in both eyes and i cant see out my ears anymore, anywho at the moment im running 3.5 pipe from the cat to a borla racing series muffler leading out into the rear panal all in true 3 1/2 pipe'n, fashion. at cruz,n speeds its decent but i think running true duels will cure the soul of the none rumble blues. therefore thats where the 02 sensor dummie comes in if i fool the factory computer wiht a dummy than i can git rid of the noose i call a catilytic converter and open her true inner beast's,
