Anyone doing it with similar mods?
Just finished my build with the same parts. Builder and I discussed the cats and thru both our research found no such specific info on ARH. I have heard of cats burning out from running to lean from the tune but I am far from an expert. Looking at my exhaust I am definitely not lean.
