Hi!

I read some threads about few of the available headers.
Some years ago, I had the Hooker 2055 (painted) and was happy with them, just the ypipe started to rust almost immediately and my header bolts had to be re-tightened once in a month.

As those headers are gone now, and my new 89 GTA will get a nice 383 engine, I'm considering to buy other ones.

My engine shop recommended the Edelbrock tubular headers, and they told me there is a set of those headers WITHOUT the annoying A.I.R. pipes.
I really don't need them. It was as pita with my Hooker headers 2 years ago, and I would prefer not to have air pipes on my new headers.

So I talked to the summit livechat, they told me there were only 4 different models:

http://www.summitracing.com/parts/EDL-68722/
http://www.summitracing.com/parts/EDL-68762/
http://www.summitracing.com/parts/EDL-68763/

I don't really get the differences between those 4 models, ok there are TiTech coated and Ceramic coated. Or are 2 of them for the dual-cat-systems?

The service-guy from summit told me about some other headers which might be interesting for me.

or

But the flowtech headers would be a no-go for me. I think the 1 1/2" diameter is too small for that 383 with around 450-500hp.


So I have slight problems on deciding which headers are best for me , especially with quality & fitment as well as heat problems (starter, wires, wire-boots). I could live with the air-tubes , but if the Hedmans are good, and the Y-pipe is good, too... I'd prefer those.

If I wouldn't have to pass the german smog tests + complete checkups every 2 years , I would stick to largetube headers, x-pipe and my cat-converter could fly away, too.... but I don't have this luxury



thanks in advance
greetings from germany

If it need to pass an emissions test, I would think you would have to purchase a set with AIR tubes. Now, it might pass without air injection into the headers, but I don't know what the tests are like. I would say, get the hedman headers and set a of stage 8 fasteners. That will keep your bolts from flying off.

Thanks for you reply.
The funny thing is, if I use Headers WITH air tubes , i would problably fail emissions tests.
Here in germany I have to clamp down the air hoses that lead to the exhaust manifolds to achieve proper emission values, otherwise I would have too much oxygen in my exhaust gases.

 

You already had the best header of all the one's listed. Though I haven't tried the headman elites I have tried the Y-pipe and it's disappointing. It rust through amazing fast and has a narrow exit.

The first two Edelbrock headers, 68723 and 68722 are the same, the y-pipe exit is 3 inch. Careful with those ceramic one's the y-pipe is just painted black and will rust fast, you should sand it and paint/treat it your self with good header paint or ceramics.

The Headmans are made of thicker gauge steel but have a 2.5 inch exit to the cat. The other two Edelbrock's you listed are for dual cat cars like you thought.

With your plans I would not pick a 2.5 inch Y-pipe exit.

Those air tube can be cut off and welded up with little effort.
