'90 OEM resonator (for fabhack)
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.

The 93-95 resonator does not close down like that. It has a 2-5/8" I.D. It is more like straight pipes. --Bob

Re: '90 OEM resonator (for fabhack)
The '96 LT4 resonator is also open & free flowing. I either heard or read that the LT4 resonator was slightly more open than the 95 ZR-1 resonator ... I have not personally measured & so can't comment other than to report what I've been told. That said, I'm running headers, no cats, and the LT4 factory system.
