New cats
This has probably been asked a million times before BUT I'm going to ask it again. I am 99.9% sure it's time for some new cats on my 03. My truck looks good but doesn't sound the best. Right now I have bad rusted stock cats with an exhaust cut out. My goal is for a LOUD and deep tone and I was wondering what my fellow 5.4 owners thought was the best "high flow" cat for these trucks. I've done a fair amount of research but I can read all day but take opinions easier. Thanks!!
