Off the shelf dual exhaust for 4WD

I have searched this topic, but most threads are quite a few years old.
Is there anyone as per title, selling a bolt on dual exhaust to suit SBC in 4WD 1st gen Blazer?
I believe Heartthrob Exhaust offer one, Part No 4159M. Are there others? Has any used a 2WD kit or a K Series one that has worked with some modifications?

If I could have everything I wanted, it would be stainless, mandrel, 2.5" engines pipes, muffler 2.5" in and 2.25" out, with pipes after muffler 2.25" and rear exit.

My truck currently has headers, and I would like to switch to cast iron ram horns. Can anyone recommend ones that fit the 4WD, or will any center dump work?
These are local to me, https://www.ebay.com.au/itm/CAL-CUST...YAAOSwd7RdPk5p

I got Corvette-style 2.5 center-dump rams horns from Speedway motors. They fit just fine.

They look very similar... It's hard to tell from the images in the listing you linked.
