Yep - they actually do that analysis. And when they're done, they actually physically test
The difference between them, and the corner muffler shop is that when they have a failure - it's not one guy coming in to spot weld a custom job. Factory recalls/service cost much more than proper analysis and initial testing. They don't always get it right - but they have some damn good FEM guys
The corner muffler guy also isn't as concerned about dropping 2dB by moving a hanger 8cm; auto mfrs. typically are. Optimizing your mechanical system could mean you can save a few dollars per car by using a different muffler
