Dynomax headers: are they any good?

Are the dynomax headers any good? also what about flowtechs? A lot of people have been telling me that the flowtechs are made in the same place as heddman wich would make sense since heddman owns flowtech.

holley owns flowtech. Dynomax headers ahve a small y pipe 2.25" and small cat 2.5". Is that good? no. Are flowtechs good? no. They are both economy headers barely better than stock. They are not for high performance by any means.

if your gonna get into who owns who, heddman bought flowtech, then holley bought out heddman, so it doesnt really matter. Some one ( cant remember where ) said that you can just extrude hone the manifolds and they flow a lot better, but I woudl think thatd be just as much money/work as putting in cheapers headers.

Doesn't Holley also own Hooker? Not a hooker. But Hooker Headers? Pretty soon they're going to buy out Edelbrock.
