The only think I know for sure is you can use an ajustable boost elbow on the HX. Im almost certain there is a difference in size but I cant throw any of those facts your way.

Diesel Doc

hy has a 9cm ex housing stock and hx has a 12cm housing most of the time so you would get lower egt's with the hx. Their are other diff like wheel sizes but the ex housing is the biggest I beleive.

HY builds boost quicker which is why they're only on the automatics
HX breathes better=cooler EGT's, but they build boost slower than the HY
Now when pulling or the addition of a programmer/module, EGT's are going to run a little higher w/ an HY, which is why some swap it out for an HX. With the addition of more fuel, it'll spool a little faster (HX) than it did if the engine was stock.

i had an hy on my 01 3500 they do get you up and moving quikly but they run out of air fast. i have an hx on there now and i like it she is not as quik but has alot more top end . hx 40 going in soon i need more air ! oh yeah and a smarty

If you think an hx35 is slow, you're probably not going to like that 40. Especially with just a smarty...
