So.. as some of you may know, the cascadia/western star onebox is not serviceable, other than the DPF's; or so i thought. After months of hearing rumours and seeing little snipets here and there on videos i would come across online i stumbled upon these guys. Recorecenters. Apparently they press out the screwed up honeycomb and they put a new one in in your DPF's.
If your DOC/SCR in the onebox is done for, or you want to replace them so you get back to having goog nOX conversion in your onebox they do it too. Gave the main phone number a call today. Looks like they have shops on a franchise basis throughout the country that do this thing?
Have you guys heard about this? Anybody that you know or even you, that did this on their onebox that you want to share more info on? Buddy gave me a ball park of 7/8k$ USD for a complete refurb of the onebox. I was thinking that if you get a used one that is at the end of their life for cheap, or even one's current onebox it may be a viable alternative to Roadwarrior/dinex aftermarket oneboxes, since i keep hearing that their quality came way down for Dinex at least.

This is not an advertisement and i am not affiliated with them. Just looking at starting a discussion on how to refurbish the onebox so we can keep our emission systems as our Freightliners age past 650k miles and beyond!
Recode the cascadia onebox? (refurbish the onebox?) aftermarket solutions to fix the onebox?
