Bill: B&B and GHL are popular header upgrades, but very pricey. There may not be enough user feedback yet on the others. Also, do you want to retain your heater?
Quality materials, proven design, expert fabrication, good customer service and ease of fit may be worth the extra $$$.
Note: if they crack in the wrong place, and you don't know it...could be lethal.
