i am looking to buy some headers for my silverado with the 5.3L, and i was wondering what would be a good brand to go with that is good quality and low price?

 

I have a set of Flowtech Long tubes on my 99 T/A They were only 230$. They are the painted ones. They came with O2 ext and gaskets too. I have had them for over a year with no issues. They are a great budget header and I am pretty sure that make them for your application. Hedman might be a decent budget header as well. I am looking at getting these for my 1981 GMC
