So I'm looking to replace my cats on my 2004 f150 5.4. I crawled up under the truck and noticed I have 4 cats total, 2 on each side. . I've read where you can replace factory with High flow cats and it will eliminate one of the cats. Is this true and does this cat constitute a High flow cat? If not, can someone point me in the direction of one? I'd like to do this at my house one weekend. Thanks.
