Well, as indicated by BlueSHO, the XSport and SHO CAC outlet ASSEMBLIES are definitely different. However, I'm happy to say, with a little bit of effort, I was able to successfully fit the SHO plastic elbow to my XSport.

The SHO assembly, however, CANNOT be used as received. As the SHO owners know, and as can be seen in BlueSHO's comparison photos below, the hoses on the SHO assembly have plastic molded clamps on either end of the elbow. The SHO elbow is also slightly longer than the XSport elbow.
The good news is that the 3" diameter section of hose (from elbow to TB) is slightly
shorter on the SHO and
longer on the XSport (by about a half inch).
Using a cut-off wheel on my dremel, I cut through the plastic molded clamps and removed the SHO CAC outlet hose and replaced it with my XSport hose and a hose clamp, leaving the shorter SHO elbow to TB piece in place (I did cut off the plastic clamp, though, and replaced it with a hose clamp). I was able to fit the SHO elbow with no kinks in the longer CAC outlet hose.
I would think (UNCONFIRMED) that one could easily do the opposite on a SHO, if desired, to get rid of the noisemaker junction. Using the new XSport assembly, remove the XSport CAC to elbow hose, and replace with your stock SHO CAC outlet hose. This would, however, require you cut though the plastic molded clamp on your stock assembly. All I did was cut most of the way through the plastic clamp, and using a large flat blade screwdriver, shoved the end in the slot and twisted until the plastic clamp separated. It's a little more effort, but will save ~$55 over the cost of the Interceptor elbow, assuming you already have appropriate tools to cut off the plastic clamps.

Now I'm just waiting on my welder to get back to me, so I can complete my boost regulator install! WOOT!
