Handling the exhaust is always a major swap consideration. Common swaps are supported by some version of stock or specialized headers, but the less common, newer swaps may not be, or you may need to save some money. In that case, most of the current Ford exhaust manifolds are surprisingly good, and you certainly won’t find a more space efficient exhaust solution. This is a stock ’03-’04 Cobra cast-iron manifold. Yes, it’s heavy, but it’s also likely “free” if it came with the swap engine, fits any engine compartment, is quiet and leak-free, eliminates the chore of snaking in a set of headers, and best of all, will support over 600 rwhp in our experience.
