I've got a cracked driver side exhaust manifold on my 99 1ton 454. Checked all the local junk yards, none to be found. Looked into headers, Gibson or JBA, can't afford them right now. Found a web store that sells replacements, 1AAuto.com, for a decent price.
Has anybody used this sight or their products?

 

I've not used them no, but you might check lmctruck.com

 

Just a thought, for $250 I got my long tube headers and y pipe, stainless steel also. Direct fit and they sound really good!

 

Yeah, I've seen some headers for around that price, but I live in California and got to pay for the air injection cr** and the CARB compliant sticker. They jack up the price for welding on some threaded fittings and a medalion.
Also, I've been told the ceramique coated geader are the way to go for longevity.
