    I was looking for a set of header pipes that did not cost to much. I was wondering if these headers are good and if the paint stayed on them. /forums/images/graemlins/1zhelp.gif

    I had a set of these. As soon as you run the vehicle with them, the paint burns off. I didn't notice any difference in performance with them over the stock manifolds.

    Headers are not an item to be cheap on. Buy the quality ones now so you're not spending more money to replace them when the cheapies burn a hole in the tubes. Cheap headers will also rust out on you fairly quick. I personally like the Hooker Competition series headers with the thermo berrier coating. If you get the Hooker Headers, get the regular competition series, the super competition series headers are made of thinner metal. The coated ones are garrented never to rust !!!!

    The ceramic coated Afterburners are $240 through Summit. I've had mine for over a year and the coating is still perfect and they fit great. The Summit part number is BIG-49152-1 if anyone is interested.

    Here they are after painting them with VHT exhaust paint. Pic taken after about 500 miles on new paint. They still look the same after 8 months.

    I just put a set on my 78 (they were free). They are a decent quality and have thicker flanges than the regular "flowmaster" headers, and the collectors are decent. I have a set of Hooker Super Comps that are made of thinner steel in the pipes (but similar flanges and collectors) on my 80. The afterburners will probably last longer (thicker pipes), but I didn't like how close they came on the passengers side to the front shackle (Hooker Super Comps fit great) ***I installed the ORD shackle kit as the originals were tweaked. They are a considerably thicker and use bigger bolts/nuts, so that may have made the situation worse than with a stock shackle***. I had to grind the shackle bolt and the nut on the 78 to make the afterburners fit without hitting. I also installed poly mounts (motor and t-case in the 78 when I did the headers) and the headers still come very close to hitting the shackle, and probably would if I had the stock worn rubber mounts. Moral of this story.....They are a decent header, but not the best fitting (again maybe due to the bigger shackles, it may not have been that way stock).
    Hope this helps

    I just put Afterburners on my truck. They fit a lot better
    than the Dynomax headers. Plently of clearance around the
    ORD shackles. I would repaint them like everyone else said.
    I had to bend my auto shift linkage a little to get it into
    1st gear.

    The rod from the steering column to the linkage does come close when tranny is in "1", but it looks as if the P.O. shortened it (looked cut, and rustier at the end). Mayhe he had the same problem with the previous headers that were on it.

    Did you put the bolts facing out or in. If I had it to do over again I would put the bolts facing out, but the shackles were already in and the Header was in the way so I could not remove the bolt and put it in from the other direction (my bolts face inwards)

    I put the shackle bolts facing in so the zerks are on the
    outside, then I trimmed the end of the bolt off. I had to
    bend the shift linkage away from the header tube near the
    top of the frame and then cut about an inch off the end
    so it didn't hit the exhaust pipe.
