The 2022 Merc compressor exit is probably going upwards because I guess it has been designed for a water-air intecooler placed above the compressor, like the Renault. But unlike Mercedes, AM and Williams, Mclaren is still using twin air-air intercoolers, which explains the look of those compressor to intercooler pipes. Yes the first pipe does half a loop then splits in 2 and the right hand pipe turns back and passes below the compressor... (a bit like Honda before they used a twin outlet compressor)
The MCL doesn't really have an undercut around its fuel tank like most cars.

The strange intercooling system of Mercedes seems to have a conical/funnel shape.
