91 F150 5.0 exhaust question..
OK.. does this have DUAL Cats?? is where the "Y" comes together a cat?? it looks like a small one. Then,, there is a pipe leading to a BIG cat.. with the "AIR" pipe feeding into the exhaust pipe in front of the cat??
So, the smaller front cat does NOT need AIR injection, but the rear one DOES?? is this right?
