Maximizer headers on ebay

Came across this tonight.

https://www.ebay.com/itm/174267467975

Shows up on multiple sellers and it seems few have bought them, anyone on here?

I see its missing the air tubes in the photos.

 

Damn those look like ARH's. With how long it takes to install headers on our trucks I would hate to find out if they are as good quality as ARH.

 

Seems to take 3-5hrs without a lift.

I tried to look it up, it seems to be a copy of Maximizer is rebranded OBX, which seem to either copy Kooks or ARH depend on the applications.

I found folks on other forums have run them:

Edit: asked the seller, he/she said its a cat-delete system without provision for EGR.
