Take care when removing by not using air tools if possible and pre-soak with penetrating spray such as PB blaster or WD-40.

the shop who installed the down pipes broke two studs one on each side. Then it’s really a pain to try and get those out lol.

Each car is different - some people get lucky. I ran into the same issue with multiple GT-Rs studs when installing downpipes. Brand new cars and cars with higher mileage.

During a recent service at my local Porsche Service Center, the technician found two broken off studs in an underbody panel. He told me they were from the exhaust/turbo manifold, but that he could not replace them without dropping the engine (not accessible). The PSC did not recommend addressing this at this time as they claim there are more than enough studs remaining to hold everything tight and no signs of any leakage. The car was in Colorado, where winter temperatures can drop quite a lot...
Have any of you had similar experiences? Should I be worried about this?

Yes. A skilled tech can get a tap in there to thread a new hole without removing the engine. If 1 or 2 are broken then yes, it is likely to suffice and seal enough without leak issues. My advice if someone has broken stud issues is to use Permatex high-temp gasket maker in addition to new turbo gaskets to ensure a good seal.

Old down pipes for sale. You can easily take these stocks to a decent cab shop and they can cut out the cat material for a fraction. If the price as it would cost for new down pipes.

I know this is an older thread, but hoping to hear some more info...

I am looking at getting a set of Racing Dynamics DT w/o cats. From other's experience that run DP w/o cats, does the check engine light come on?
I have a scan tool and can reset, but not wanting to do this all the time...
