it seems it would be infinitely easier to remove the muffler from the bracket using the the 140mm (fore) and 70mm (aft) bolts that hold the the muffler to the bracket.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

not to question the eggheads in stuttgart, but is there a reason why some bolts are placed in a particular direction? ie, why the bolt head is on this end, and the nut on that end... and not the other way around?
ive been working on my exhaust, and it has been a bear to remove. i ended up cutting or drilling most of it off/out.
all of the writeups and directions say to get at those three fiddly bolts that hold the exhaust bracket to the car. if you've tried to work on your mufflers, you know exactly what i'm talking about. as mine were not only difficult to reach, but also rusted beyond recognition, i ended up just drilling the bolts out through the outside... and welding new bolts in after.
but that's not where the question arises...
it seems it would be infinitely easier to remove the muffler from the bracket using the the 140mm (fore) and 70mm (aft) bolts that hold the the muffler to the bracket. rather than remove the bracket from the car.
but of course you can't, because even if you were to undo the nuts (bottom side), the bolts would foul on the heat shield and body work above, impossible to remove.
so, is there rationale to having these bolts with the head up, nut on bottom? rather than the other way round? in which case, you could undo those nuts on the top, the bolts would fall out the bottom, and your mufflers would be off.
ah. good. well that's what i did as well.
and replaced everything except the headers with the ipe valvetronic setup. some may poopoo it, but i couldn't find another non-porsche-sport option out there with switchable modes.
will report back later.
Well, technically speaking , IF the bolts were installed with the bolts coming up from the bottom ( nuts on the top) .. IF the nuts were to come lose, the bolt would fall out !!
This may be beneficial for easy access, but for "failure analysis" you would rather have the nuts on the bottom, so that IF it were to come loose, just the nut would fall off but the "through-bolt"" could NOT fall out...no matter what !!!
Note :::many thing are done this way that may seem "counter-intuitive" , but if you think a little deeper , there are safety reasons engineered into the decisions..
