there's the link to Jegs. Anybody used these headers?

What are the dimensions?

 

From what little I have read about them they work better on older camaros and firebirds, like the 60's and 70's models.

I run a set of them. I got them from nextgen for $370. That included the ceramic coating, a y-pipe and everything you need to put them on. One word of advice; don't use the supplied gaskets! I did and it has come back to haunt me. Also, a unique feature of these headers is that they have 1 1/2" primaries, some say this is good, some say it's bad. Here are some links with more info:

I want to know who says 1.5 primaries is good. Especially on a 350.

 

yo bro the afterburner flowtechs willnot fit your car
you must get the flowtech headers disigned for thirdgen f bodys
i have them and they are great
i got them for $190 including headers and y-pipe from the local speed shop
they fit better then alot of the more expensive ones and if you have a 305 i would highly recomend them
and plus if you take out the cat they make your car sound evil
i love them
if you have a 350 then i would not get them considering the primarys are only 1.5"s and the y pipe is 2.5"s
if you ahve a 305 you should get some hookers

 

Momar-take this for what it's worth, it is just hear-say. This is from a current post on the aftermarket review board about flowtech's:

Regardless of the accuracy of this info, I think they were a good choice for me. My engine is still stock, with the exceptions of a few bolt-ons. Because of this I would imagine my overall power curves look better becasue of a bit of extra backpressure. From what I understand anyway, the big advantage of headers isn't just the increased primary size. It is the fact that the pulses of the exhaust gases from individual cylinders don't have to fight for space in the single runner of the stock manifold. On top of that I would think that any hp lost due to a small primary size was gained right back becasue of the ceramic coating that mine came with.

There are hundreds of variables acting here but the fact is Flowtechs are a decent and affordable SLP alternative!

I didn't mean to go off on a tangent, but some people on this board come off as SLP salesmen. I agree, SLP does have there $hit together, but there are other, cost effective, alternatives out there.

 

I totally agree that they are a lot better than exhaust manifolds. Also I am in no way trying to get others to buy slp. I actually am going with hooker long tubes myself. Oh, and as mentioned on many other threads "backpressure is BAD". You do not want backpressure. You want scavenging. If you go with too big of pipes or the wrong setup you can loose scavenging effects but the less back pressure the better. I think that they flowtechs would work good for a 305 or possibly stock 350 and they look nice ceramic coated, but if you are going to have bigger cam, better flowing intake/heads especially on a 350+ cubic inch motor you might want something with at least the 1 5/8s primaries. But just to restate, I am not trying to order anyone to get something specific. I was just giving my opinion.

Dustin Mustangs, did you have to use any shorter plugs when you installed those headers, and did you use angled plug wire boots, straight ones, or a combination of both? I'm just trying to get as many parts lined up ahead of time as possible.

 

you should have to use shorter plugs but its definetly harder to change my plugs after my hooker header install which wasnt to fun i might add

 

I'm getting the Flowtech shorties. I didn't know if they would be any different or not. If I need 90 degrees boots on all 8, I was going to order them tonight when I order the headers, so as to save an additional shipping charge later.

 

good boy eric
the flowtechs are great

 

The stock plugs worked fine for me. They are still a pain in the a$$ to put in though. If I were you I would try to put them on while there isn't anything on the head if you can, ie. after you take off the manifolds and before you put the headers on. This might create some clearence issues, but if possible it would save you some time and busted knuckles. I used a set of accel wires that included some straight and some 90` boots and I still haven't roasted one yet. So they will both work, but if I could do it over again I would use all 90's. You should also consider droping some more loot on a set of wire looms. Check out the 'Made for you' post on this board. Oh, and one more thing, I would not recomend using the supplied gaskets. I did and it looks like I have to do the whole installation over due to a header leak that is skewing my 02 readings and killing my milage. Feel free to bounce any more Q's off of me.

:rockon:

 

Damn, I thought they were 1.5" primaries with a 3" y-pipe.

2.5 is worthless.

 

Yeah, I figured that about the gaskets. I'm planning on ordering aluminum flange gaskets and either copper or aluminum collector gaskets. What are the collector gaskets that come with the headers made of? Would you recommend using those or not? Also, do I need round port or square port header gaskets? I think I'll go ahead and order a set of 90 degree plug wires too. As for the looms, I was looking at a set or Moroso looms. I have perimeter bolt valve covers, so I'm not sure if the Made For You ones will work. The moroso's are cheap, but they look like they'll get the job done. They look similar in principle to the ones you have; they're not the big forked ones. Also, how do those looms attach to the valve covers? Do they fasten under the valve cover bolts? Thanks for the info.
