I have a 97 f150 with true duals and 5in tips. I want my truck louder i have two cats and two resinators with four o2 sensors i know i cant get anymore sound than what i already have without cutting something else off. Now the question will it make my truck run any different and how mush more sound are we talking

 

If you want REEEAL loud i would chop the cats and the res.. and go straight piped.. buy some o2 dummy sensors... but then again not so street legal....

 

not being legal dont bother me but how mush power loss will i have and were do i get the o2 simulators

 

well.. if money is no object slap a set of headers which will up the noise some more.. and personally i dont think you will lose any... if any.. verry minor and not noticeable.. and if you google o2 simulators many hits will come up.. or ebay is a great way... im having trouble finding a sensor myself..becuase it's an older truck but you will have no problem ordering one.. prolly $10-40 and easy installation
