If I remove two of the three cats. in my factory exhaust with headers, do you think it'll still pass emissions (not visual)?
NOPE
I've got the Kooks green cats on my 6.2... Wish I had that HP to test it out !!!!
They don't make them anymore - nor the headers - for our beasts
They are the "bullet" style.. So with my Kooks 1 7/8 headers and the kooks Y pipe with green cats
I don't have to remove any exhaust to drop my transmission pan !

Oh, bother.
I want headers, but it just seems like a chore to deal with getting them to pass NH emissions.
I know shorty headers do nothing for flow/power, but they cost the same as the cast manifolds, and at least look cooler.
My 6.0 rebuild/swap engine is gonna need something. I think the 5.3 manifolds are warped or something, and would be replacing them.
