It is right that when you do not have bass problem then why to do any absorption for it ...
But how do you know you do not have any problem ?o0
To make it simple and easy just forget about the impedance : it happens this way
you have distributed mass acoustic in your fiberglass which can be effective somewhere >150 hz.
and in sealed design it can be effective below 150 hz down to 20hz in large tubes+full MF HF absorption or diffusive.
actually your insulation pipes already do absorb 80% mid FQ(150-500hz) and all hf FQ where they placed.
if you think you do not need to go below 150hz then just try to make your tube fiberglasses well structured from within and covered hardly from outside.
Acoustic Z of trap is useful in sealed design then just nvm it.
