Any way to tell? All I know is that they reach the bottom of the engine,(i still think they are shorties)
and are ceramic coated, and do not change color when hot, never.
Any info would be great, but I know this is a tough thing.

SLP's will say SLP right on them, not sure about the Dynomax, Headman or Hookers. Edelbrocks I think are coated Black but i could be wrong.

 

Are they Tri-Y or 3 into 1?

 

The header tube diameter will give you a big hint. There are a fair number of generic companies that make 1.5" primary shorties. Flowtech, Summit, Dynomax, etc.
If they are 1 5/8" then there would most likely be some sort of manuf. identification. i.e. a plate on one of the primaries telling you who made it.

 

Great tips, I'll have to check for a plate on the tubes then, I just cant get to the passenger side yet..
The reason I need to find out is to correctly find
2 y-pipes to replace my leaky one's right now.
I was told it's called the y-pipe, but I 2 single separate pipe running from each hedder to each cat.

 

hookers say on them too

 

Not all SLP's will say SLP right on them, mine don't.

 

Sounds like it's going to be tough to determin, I wonder if it's possible the name may be stamped only on 1 side, the passengers... when I get down there I may find it, let's hope.
When I do the valve steam seals, I will take a look and some pics..

 

Both of the sets I owned didn't either. My Accel headers don't have any ID on them either.
