Gutting cat
Are there any benefits/problems with gutting the cat on a 1997 F250 7.3? I do need to do emissions testing here in Maricopa County,AZ. Will mpg/performance increase or will gutting be a problem and not be worth it? Thanks!

We have to test emissions here every 2 yrs. Last time I tested with the cat deleted, still had the muffler. I was afraid it would not pass with superchip set, after they double checked and all it passed, I hope i'll be as lucky this year.
When i did my first mods intake and exhaust i pondered over gutting the cat or deleting it, I deleted it and still have it in my garage if i ever need it.
