I'm in the market to buy a header for my SS/SC. Does anyone have/know anyone that has the SCdyne Header on their ss/sc/ion rl?
What are the specs on the header? What are the gains?

Here is the webiste:
http://www.scdyne.com/exhaust.html

1-3/4" primaries and features a 2-1/2" collector
Cost: $399.00

Also, what other headers are out there? I know TOG made one, but it seems that people were having fitment problems and gasket problems.

05 I have seen some complaints about the SCDYNE headers. I personally will wait to swap my header until at least late summer. There should be more of a market then

I've done a lot of reading up on it. Seems like the first header they came out with wasnt that nice, and had some problems. But then they went with a different manfacturer and now its supposed to be a nice header... Just want to know if anyone has one and what they think.

I have one on my car since a couple months and I didn't experiment any major issues. First week I got it installed, I get a little crack on a weld but got it fix by a welder. Maybe not the best quality, but the design get really the job done. I used the stock gaskets without issues, but we had to grind the largest flange a bit. Expect 10 whp or a bit less, because the most restrictive part on our car is not the header but the exhaust head itself and the rear muffler.

You cannot ask for perfection from a 400$ part since there is some header that will be out soon for 700 $ (Vibrant Performance).

The ceramic coating is peeling a bit too, but the header is mostly hidden behind the motor so you don't see it.

Also, these SCdyne header were made in the past by Hotshot, but now I think Adam got another maker for them. Since I am not sure, just PM him or e-mail him.

I would recommend them for the good design and the flow gain. To me it's the most important.

The collector is 2,5" so if you plan to go 3" in the future maybe it's not the header for you. But most of the catback companies went out with 2,5" catbacks.

I would stay away from the GMPP header, since it flows only 30 CFM more than stock.
