I stand corrected on the starter then. My Jegs also use the stock starter and stock oil filter and both will go off and on w/o that much drama. I say crappy tongue in cheek. I personally don't think the $100 Jegs headers are crappy at all. They are every bit worth 1/2 as much as the TTis if you ask me. If you ask me the coated TTis should be about $500 and they should sell raw ones for $300. Then I'd think about it.
The $300 carb is actually a great example. There is much more engineering, cost, and assembly time in a 4bbl carb and they are $300. Headers for more then twice that seems out of line IMO. The factory manifolds are not a good comparison as they are a collector piece, some folks have to have those parts for a resto and they didn't make enough to match supply.
