I'm currently running stock manifolds and Roush Off-Road cat back system. I'm thinking I need some headers also, my neighbors may not but I do. I've searched and read many threads and I think I am going with the Dynatechs. So far part # Dynatech 122-842200 from summit racing is the best I can find.
Is this the right part # and anyone know where I could get the best price (without using Ebay).
2005 F150 Lariat Screw 4x4 5.4
thanks

 

be careful when looking around for the full system. Someone might try to short you parts.
