well a header is kinda pointless since the extra gain you get would have to pass through the restriction of the huge stock cat...if your not gettin both then i'd say go with the downpipe first but you can get both at a reasonable price (zzp midlength header/dp)

A header and hi-flow will definitely be the best performance gain over just one or the other. However, the stock converter is not as restrictive as the stock manifold. The stock down-pipe with converter can be modified to work with a mid-length header to save you some cost.
