While you did that modification, we did this on an 84:
Bolt-on a 32V 928 stock cat system that somebody removed (dual pipes out instead of single).
Weld a Y-transition to the above. (dual in, single out)
Cut the inlet flange and a couple inches of pipe off a good 84 cat-back. (single pipe system)
Weld them together. 85 cats to Y to 84 single pipe.
Why? 84 cat is restrictive / downpipes rusted away on mine. I couldn't find an 84 cat locally.
84 cat-back was solid as a rock! They make these pipes almost bulletproof.
Only ancilliary modification: must cut a slightly larger hole in the front heat shield to accomodate the location of the 32V oxygen sensor portrusion.
Solution cost $100, total.
