Everyone, im looking for some new headers for my '04 5.3 ltr. gmc. my warranty just ended o its time to do some more mods. what headers do you reccomend when it comes to ease of application, looks and of course the most performance gains. i also would like to replace the cats with hi-flows at the same time. thanks for the help.

Dude you and me should be the official PT.NET Post Police

 

haha, this is the first time i have used this forum. im usually on ls1 tech. thanks anyway though

 

Well I do my fare share of asking questions but I cant recall where somebody told me to do a search. I always search and read until I get tired of reading then I ask if I cant find it.


To somewhat answer your question so you dont get mad.. Get you a set of pacesetters with an ory. (most common) The cats you have now dont flow awful. Unless you live somewhere where you have to pass inspection I wouldnt even worry about cats.

 

thanks. i want the cats mainly so i have a full exhaust system. i usually search if i dont know where to look but i figured i would just save some time.

 

I have the Stainless Works Headers and love them.
