    I'm getting ready to put dual on my '87 Jimmy. I have started looking at Jeg's and Summit for headers. I want a good set and I just got done reading that post about the leaking, so if at all possible, I would like to get a good set for not a too expensive price. Like below $250. Later

    Like I said before, I have the Hedmans... they are thin and cheap and rust and I'll proboably replace them next summer if this coming winter does hell to them. The Hooker super comps look nice or else the Flowtechs.

    NEVER been stuck... *yet*

    What's the big deal with getting the headers coated?? I hear that it helps the headers, but why is it good for them or whatever??

    No rust= No leaks/wear/holes
    also helps keep the engine bay cooler witch is good for the intake. Other than that, ??

    Like the man said, they last forever and should keep the heat down some.

    headers suck ass and lead period go with early 60's ram horn exhaust manifolds and you will be hella happier in the long run

    Anyone ever have the flowtech headers "jet-hot" coated? Or do they come that way?

    I have had the Flowtechs for about 6 months and the are already pretty rusty. I haven't had any leaks yet though and for how cheap they were I can always just replace them in a couple years.

    I've got dynomax headers and matching exhaust. The headers have a nice thick flange and haven't leaked on me yet.

    A ram horn exhaust manifold, while more durable, will never be able to equal the horsepower building ability of a good set of headers.

    As far as coatings go, it all depends on where you live and what coating you get. I've seen people send back coated headers multiple times because of chipping. Header wraps can also work well, though they can trap the moistur and lead to early failure. If your truck doesn't run hot and you're in a dry area, you don't really need any coatings at all.

    I'm with Grey Thunder I run Dough Thorley's and I love them no leaks and they improved the performance of my truck really good although I still need to get my new mufflers so I can run the headers through 21/2" pipe that way I can get all the power that I want good luck.

    keep blazin !!!
