detroit scr demandatee box

[gsain]

Has anyone ever had experience with the {name removed} box? I saw this video of theirs claiming to connect it to the SCR box connector and just bypass the exhaust. From what i have learnt, it tricks the computer to think the SCR box is working good while bypassing the exhaust with a different pipe. But what i think is the problem is that instead of the exhaust passing through the DPF those restrictions are removed and it directly goes via a pipe. Would this effect the engine or ECM in any way?I have linked the video below.
