Headers

Are the headers for the S550 the same as for our cars?

No, completely different than the 5.2

exhaust flange points are the same though right? Is it just a matter of fitting the car, or tuned for different lengths because of the engine?

The S550 5.0 cars use an integral "mani-cat" on one side whereas the GT350 uses separate manifolds for each bank.

I guess what I am getting at, if I had a set of GT350 headers (not stock) would they fit a 5.0L car and vice versa.

Do note that the firing order of the Voodoo and the Coyote are different and thus the stock headers were tuned as such. Because they are not a 4 to 1 configuration, I would definitely advise against this...if they would fit.

If you look at the other headers on the market....they really don't appear to be anything different. They are all 4 into one headers using a 3" collector. They have different primary sizes, some are 1 3/4, 1 7/8, or 2" and Kooks is the only one I see that has a stepped header. I do not see a Tri-Y design on any of them or different orientation of the primaries going into the collector

Correction...I definitely missed the NOT stock part. I see what you're trying to do now. Yeah, I would definitely be careful about this, starter clearance, the main pipe mating up to the mid pipe from the headers etc.

So far, everything I can find is that it is the same header between the two cars......save for Kooks which is the only one that is doing a stepped header design for the GT350 cars. Everything else about the headers seems to be the same.
