I have a full 3" system on my 84 SVO including downpipe and cat. I had the
system made locally except for the downpipe which is available from a
number of vendors (I can't remember where I got mine from).

The differences between 84 and 85.5 SVO's that I can think of are:

Revised calibration air flow sensor.
Lower a/r turbo in 85.5
Addition of water cooling to turbo
Revised intake manifold
Different cam
Improved exhaust manifold.
Dual exhaust
Revised calibration ECU
Injectors increased from 28 lb/hr to 35 lb/hr.
(There does not seem to be a consensus as to the flow rate of the 85.5+
injectors, the brown ones. I've heard values from 32 lb/hr up to 36 lb/hr,
suffice to say, they are larger!)

Ok, everybody, what did I miss?
