So I do most of my own work but I'm contemplating letting a well-known local shop do the install of a 2.5 AEV lift for me. (2012 JKU Rubicon)

I'll also be installing 35" trail grapplers

They're saying I need an AFE cross pipe. Is this correct? I hadn't seen this in my resarch on the forum.

Any feedback much appreciated.

You will need either that or exhaust spacers for the 2012 & 2013. The exhuast is different than prior years and your driveshaft will touch the boot and destroy it. Some folks say theirs didn't touch but mine sure did! I used Teraflex spacers on mine. There is a video on it on the Tflex site. I wouldn't chance it myself for a simple fix.

also there are some clearance issues with afe in combination with manual gearbox...

AEV says not needed.

Confirmed. Have the 2.5 DS XT. I even called AEV to discuss the install and verified no exhaust mods (pipe of spacer) needed.

I saw that on the Teraflex video too. That's why when I called AEV about alignment specs, I specifically asked them about an exhaust spacer. They said it was not needed. I've been running it for a year now with no issues. I also have a JKU - which may lessen the driveshaft effect.
