Hey whats up? Im building a drag header right now. I have all the lengths calculated for the primaries, the steps, and the collector. its a 4-1 design, using burnsstainless merge collector with megaphone. The header right now is for my friends H22 drag car, soon i will be fabing one for my k20. I was wondering if theres anything else anyone can tell me about the actual faberication of the side exit drag header like the bends (too aggressive? too many?) or like welding or tolerances in the lengths, etc. Anything will be helpful. thanks.
