Jardine header is better than the V&H header. Looks don't mean anything. I can polish up and anodize a 2" pipe, doesn't mean it'll perform worth a crap.
Jardine is one of the best off-the-shelf headers for the Blast. Mated to a D&D can and you have about the best off-the-shelf exhaust possible. Next to that would be a Supertrapp can on the Jardine header.
However going custom, possibilities are endless. Cheap $100 welder, $50 in metal and I have a new exhaust. $50 for more metal and I have a 2nd exhaust. Etc, etc. Right now I'm running a Force clone, for about 1/5th the cost. Next is similar to XB9 dimensions for ... guess how much? $50.
