(note: the headers might be different than what is pictured)
FlowTech headers are precision engineered and leak tested to get maximum performance and fuel economy from your engine. Each header is formed from specially selected .049 cold roll flash controlled tubing, and features FlowTech's exclusive, thick, mandrel-formed Power PlenumTM collector. All ports are precisely fitted and finished with sturdy, leak-proof O-ringed port seals, and all FlowTech headers include all mounting hardware including bolts, nuts and premium gaskets.
FlowTech headers are available with either a high-quality, electrostatically-applied PPGTM satin black paint finish or with a specially formulated, NASA-developed silver luster ceramic coating for rust and corrosion resistance.

Precision engineered for fit, performance and economy
Includes all mounting hardware and premium gaskets
We have them listed for various 1999-'02 trucks. FlowTech hasn't installed a set of these on a 2003 or '04 so they can't confirm fitment for those years yet. Off the record I think they will be fine. Ok, now this part isn't a typo... pricing for the uncoated headers is $249.99 and $409.99 for the ceramic coated version. These are designed to bolt up to the factory head pipes and come with everything required for the install. More info and part numbers can be found on our website.
