Installing a Larger Cat Oil Filter on a 6.6 Duramax

I think we've been over this one at least twice...
IIRC the verdict wasn't good...

I didn't realize that this info had been posted.
It looks like a very simple installation. What was the problem?
Well, just using keywords "Duramax cat filter" in the search feature on the board I hit this almost immediately

I did not read that entire thread, only enough to know it's on-topic.
I did not look at further search results. I do not care enough.

Nice mod so now replacement oil filters cost $30 instead of $6 
The only one i could locate quickly was the same one D60 linked. I do recall as i said in that thread that there was another more extensive one. I recall that @dnewton3 had made at least one post in the prior one.
Since i don't have a duramax i did not absorb it past curiosity.
Sorry i can't give more detail.

Maybe you can fit it to the 2.5 and double oil capacity?
I've never heard of any oil related issues on a Duramax.
Sometimes stuff like this is just people wanting to make their pickup more like a big rig or dump truck. Got to have a CAT filter if you're going to get the big jobs.

What's the reason to do this? Don't those engines out last the rest of the truck even with the stock filter?

Ray is starting to succumb to too many internet lore stories and he’s being influenced by too many fly by night “influencers”
I'm starting to lean in that direction as well.
My interest in this system stems from hearing the Cat filters are well-regarded and because I used a similar oversized filter on my two 7.3 Powerstrokes with good results.
He's gotten big enough that people are starting to give him things. Can't say I'd blame him, I'd take free stuff and put it on my car too, so long as it wasn't complete BS. If Banks came knocking with some free swag, there would be Banks stuff on my Ranger.
Free stuff rules !
Exactly. He took "oversize oil filter" to the next level, and then one more level. Oversize oil filters can be a good thing, for certain applications / circumstances, but this CAT commercial filter is just... whoa. I mean, dang bro.Nice mod so now replacement oil filters cost $30 instead of $6
At first I thought he installed this kit only because it was gifted from a subscriber. But the video doesn't mention a gift, only that the kit was found on Facebook marketplace. So Ray may have purchased this kit himself. Also I wonder about that small clearance from the prop shaft.
He’s tight with FordBossMe.
Most of the links in this old tread are dead so i'm not sure its the same adapter, but:
