'90 OEM resonator (for fabhack)

[Schrade]

Does someone have cutaway snappics of the early resonator?

I thought I saw it on Marc's site, but no luck finding it so far here. And NOT just showing the restrictive inlet; rather showing all the innerds. LINK???

Reason I ask here is that these 3" pipes are just a little over the limit WRT in-cab drone.

First thought is to use the factory resonator, with the inlets and outlets zipped off [OUT], and the 2 x 3" sections welded into the resonator inlet and outlet, and bolted back into place, after the X-section here:

edit:
Found it - looks like the entire core is 1 5/8" throughout.
