If I can use a S muffler what years would I be able to use. I don’t want to have 600$ spent on a S muffler that won’t fit or won’t work correctly (I heard pipe sizes were different which may lead to power decrease)

That's right]

The one thing I would keep in mind is that the tips on the facelift mufflers are removable, whereas the tips on the pre facelift cars (if I'm not mistaken) are welded on. So if you were to buy a facelift muffler with no tips (as they are sometimes sold since some dismantlers sell the tip separately), you wouldn't be able to simply unbolt your stock tips and swap them over.

Would you suggest just getting a non S muffler then? Or does it matter since the muffler is getting modified(not sure what exactly they change). I would try to find one with the tips like the other guy said. There’s plenty more options if I choose a S muffler but if it’s gonna kill power then idk if it’s worth it to get nicer looking tips

Unless you are installing a bigger engine you will slow the exhaust flow with bigger pipes. Porsche does alot of testing before settling on a part for production.

Have you ever squirted a garden hose? To make the water come out faster & farther you have to reduce the exit diameter with your thumb!

I have a stock muffler design on my 3.6 litre engine.
