alex.t Posted July 4, 2010 Report Share Posted July 4, 2010 you can take them out but when you get your tune include in your info that you want the sensors deleted then it wont throw codes Quote Link to comment Share on other sites More sharing options...
Mike Frey Posted July 4, 2010 Author Report Share Posted July 4, 2010 okie doke, and another question when i do the cat delete do i have to buy a cat back system? thanks for your help Quote Link to comment Share on other sites More sharing options...
alex.t Posted July 4, 2010 Report Share Posted July 4, 2010 well if you cut the cats out you'll have to replace them with a exahust piping to fill the gap or you can hollow the cats out and put them back in. when you say catback system that would mean replacing the whole exhaust from the cat back, its not necessary unless your plannign on changing the whole exahust.

alex.t Posted July 4, 2010 Report Share Posted July 4, 2010 ya same thing except you have some fake cats under there just incase somebody ever questions you and wants to take a look. are you doing this yourself? Quote Link to comment Share on other sites More sharing options...
Mike Frey Posted July 4, 2010 Author Report Share Posted July 4, 2010 yes i was going to it myself, because the muffler guys were i live arent allowed to do anything involving removing the cats or hollowing them out. Quote Link to comment Share on other sites More sharing options...
