Default Custom exhaust shop capability

How well should a competent exhaust shop custom be able to bend a midpipe so that it sits high in the exhaust pipe channel to maintain ground clearance as stock? Also curious if this process is trial-by-error (eyeball?) or if they would use a template of some sort (computer?) for fitment accuracy. To me, clearance may be the difference between getting a custom job or sucking it up and buying a Stromung, assuming their fitment is good.

Also, assuming a stock header and cat section, would an unresonated midpipe coupled with, say, a Borla or other "moderate" universal muffler be droning or stupid-loud?

Exhaust shop should be able to do this. When I bought my RS, my stock midpipe would drag on speed bumps or unlevel surfaces (my car had lowered springs). When I got a custom 2.25" catback installed I gained about a good 1 to 1.5 inches of clearance. Just enough for me not to scrape on all the places I previously had. BTW my catback was unresonated and it barely made the car louder. It lowered the tone of the exhaust a little bit.

It won't be loud unless you take out the catalytic converters. Now I'm not saying, that if you leave the cats but put a huge coffee/fart can as the axleback it won't be loud. That would definately cause droning more than taking out the resonator. Other may have better input from some of the aftermarket catbacks. GL!
