I've been wanting to do a Cat delete on my 2011 RAM 1500, with the 5.7 Hemi. I've currently got the bullydog GT plus for hemi, AFE cold air intake and just a muffler delete. I'm wondering if anyone has tried to remove the cats yet, and if anyone knows if the tuner i have will permanently remove the code(s) that the o2 sensor is obviously going to throw if i do this. I haven't heard or read of anyone doing this yet. Some feedback would be much appreciated.
