no. no one makes headers for it. you have to have them custom made or have the manifolds ported. heres a couple links to get you caught up as to where everyone is on this topic. im actually thinking about having them custom made i have to invest in a ski mask first though.

your only option so far is hand made. i think hooker has the lsx flanges.and they have the 4 in to 1 collectors and then just get some J bends and go to work.

 

..Jean Louis, maybe you could start a side business & make big $'s making Header's for the 5.3 L Thanks for all your contributions to your MCF Family...It's appreciated 4-Sure : )

Oh, what do you think you would charge `if you could, or decide to start a business on the side ? Is it difficult to do ? Thanks

 

You can look up doug thorley they make headers for the 5.3 ls4

 

Well, if you can't find any headers, there's always this that you could add to the exhaust:
