More flow through the bypass system is not a good thing.

Increasing the outlet diameter should have very minimal impact on the oiling system or bypass filtration. I run the SPE Oil Filter manifold and see a 2psi decrease but a 12% increase in volume at the turbo oil feed. After adding the bypass oil filter no perceivable difference in pressure was seen, but, I have not done another flow/volume test since I borrowed the flow meter.

Personally I would leave it. I would be weary of work hardening the outlet adapter causing it to become brittle creating an issue with hot/cold contraction.

gotcha, truck has been running good, I’m probably just overthinking ****, frantz claims it doesn’t decrease flow or pressure and I’ve made it bigger so

I also doubt the adapter you drilled out is a significant restriction.
You could try shutting off the bypass flow to see if the typewriter noise fades away. Could add a small inline ball valve or pinch the hose with a hose pinch clamp to do that test. I’ve been rethinking bypasses for a while and, if you run through the math starting with fresh oil, you only need to bypass a small flow (3% is plenty, or about 1/2 gpm on the 6.7) to maintain +2um particulate to nearly zero.
Just curious, what is the ID you drilled out to and the ID of the OEM adapter?
I’d also be interested to know what instrument you used to measure turbo oil flow F250_Super_4x4?

I do not know, I have a friend who is one of the mechanics for a pro stock drag car who has one. They use it for fuel and oil flow under max RPM and Load. Its a box with bluetooth to a monitor that shows flow, pressure and Delta from an upstream or downstream location.

Really am more interested in the housing itself than the Cat filters, truthfully. But there'd be no running an OEM sized filter on their housing.

Now I'm looking into that SPE oil filter housing... I like those larger ports for more flow, hence more oil pressure under throttle applications.

What they do not have is a bypass on them which causes many people concern in very cold regions.

it has 5w-40 and about 4k on oil, also with two quarts of Lucas in to help with oil starvation on cold starts, I was thinking the same thing with the bypass filtering out all the soot and brand that the oil is so clean that it’s not masking the noise, just wanting to make sure I’m not hurting anything by running the frantz by pass kit
A complete scam.
