The great cat debate. I need answers!
I have a 04 5.4 with a bullet and an exhaust cut out. I want a louder, deeper, more rumbly tone. I've been reading around the forums and I've decided replacing my cats is the best idea. The only problem is that there's different ways in doing this. I've read about replacing all 4 cats with 2 hi flow cats, leaving the pre cats and deleting the rear cats, and vise versa... I've read many contradicting threads and pretty much all I want to know is,
Which cats should I keep? Which cats should I delete? And with which cats should I replace them with so that I get a good sound, pass emissions, and get no CEL?
