I will listen to this one for a few and switch it out to the other and listen to that for a few and decide.
I just wish I had a garage. I try to avoid drawing attention so do my swapping after midnight.
Pic of carpet on ceiling, both seat backs down and the 40 split side down which I normally do so I can push it up and down quick if I'm making a stop somewhere. Having both down doesn't make much difference to these ears.

Duratex on order from parts express.
I need to clean up the wiring and secure the amps.

Ok. Large box seems more boomy and smaller is more peaky. I feel the bass impact more from the drivers seat with the smaller box.
Decisions...decisions.
Don't know which box to go with.
Is the 3.28 @ 41.12 as extreme as it gets?
I know there has to be a point to where the sub loses control due to being in too large of a box.

Gonna keep the 3.28 @ 41.12
Filled all the screw holes ready for Duratex.
Thanks everyone for help especially Shredder2
Can I have a mod take this thread back to the OP Denim with his posts and replies and anything related to my crap be in it's own thread?

Nah don't want to go there.
Would a round port 3.28 @ 41.12 be smaller and more efficient?

Last box is heavy as heck.
Now I'm building the back firing aero box out of 7 ply pine. Seems strong enough. A lot lighter and less dust.
The SDR-35 riser pipe is 5.75" internal, 6.25" external.
Don't care if it isn't as loud as the last one this is lighter and has less width so I have more room to remove my jackstand, jack, cables etc that are stored on the sides of the box.

I will flare both ends of the port and I still need to round off the 3 inch brace for the baffle and the ends of the port support Also need to make the second baffle
Sounds as loud as the last one to my ears.. Wasted the Duratex on the last one. Caulking would show through stain. Probably get some more Duratex.

I'd measure 1/2 front radius to 1/2 rear radius for length, as long as you're close the tuning change ought to be slight anyways if a roundover bit is used.
If actually flared it will change but only slightly and the same way of measuring length ought to apply.
The displacement changes using a small flare ought to be slight, using a roundover even less.
OP shouldn't worry... a 5.9id should be overkill anyways
It's actually 5.75" inner diameter 6.25" outer
I just got rid of the sharp edge so rounded it over some.
A flared port I believe you need to add an inch to the length?
My port is working fine.
