No aftermarket header even catted ones will guarantee tou wont get the P0420 cel code. See the Basic Bolt on mods guide link below
Any aftermarket header can result in difficult warantee claims for engine problems as your removing and replacing vital engine sensors and moving positions of o2 sensors reliative to stock positioning. Manufacturer could claim that this resulted in changed fueling to engine. Also increase in heat in engine bay due lack of heat shields causing deterioration of components or belts or resulting in higher engine or oil temps.
If your rearly conserned about warantee then dont mod stuff.
They cannot just deny claims, but any mods give them an oportunity to deny or partially claims if they can tie in mods to the failure or accelerated wear or deterioration on components associated with mods
Remember you will be arguing with trained engineers technicians and lawyers and a company with lots of money
