Holley tubular swap headers MIA on website. Reason?

I looked under headers for Gen3 and found these:

https://www.holley.com/products/exhaust/headers_and_exhaust_manifolds/mid_length/parts/BH2584
There was also a set of silver ceramic one for the same price and black painted ones for $100 less. That's 4 types in all if you include the Chevy set above.

Interestingly, only the GM set are on clearance.

Have to say, hard not to jump on a D100 set just in case I ever want to build a G3 swapped pickup.
