73 MFI muffler- what is "stock"
The muffler on my 73 RS is finally dead, and I'm looking for the "stock" replacement. I have checked Stoddard, and they have a muffler, part number 911-111-025-00, for $380. This is the correct original muffler part number. I called to ask for the origin, and they only know that with that part number they are sourcing it from Porsche- at least that is what the parts person said.
I'd love to stay "stock", which to me means a NOS muffler from the original supplier (Leistritz or Bishoff maybe?). However, if those are NLA I'd rather just get the current supplier's muffler through the cheapest source possible. In other words, if Dansk is now the supplier, am I getting the same version here as I would from Porsche, and saving $100 in the process? Any help is appreciated. I've read the muffler threads here and I'm convinced that "stock" is the way to go for best overall performance, at least for me.

Correct, 911 111 025 00 is the original number.
You are also correct about the real challenge, which is finding one from Leistritz or Bischoff. These will have "ridges" on the inlet pipes and wrinkles on the inside radius of the outlet pipe where it was bent. These are also stamped with a date code. That REALLY makes it tough. The code on the one I have for my '66 is 1969. This is a quandary right up there with finding an original battery, as these were a wear part. If your RS is a "driver" I would get the stainless dansk ($$$) and keep your powder dry for the real thing. Good luck!

Yes, I think you're probably right. I've already made a similar choice by going with SSI heat exchangers, although I made that choice 12 years ago before car values, and concerns over originality, got so crazy.
The car is a driver. Never should have gone to the Parts Heaven concours this past weekend. It's always bad depressing comparing a driver against those concours-prepped cars... At the end of the day the most important thing is that the new muffler matches up well with the MFI system, so I think Dansk is it. Thanks,

Well Jeff, my view on such things is that if it takes 15 minutes to bolt on or off, who cares?? Concours cars are great, but they're really more like art....except you have to go to the garage to see them, and you're wife thinks you're crazy, and you still have to spend a gazillion dollars on REAL art for the living room, LOL.
Keep driving...thats the art!

funny thing is that allot of mufflers work well with many different mufflers. Our sports work great with MFi and so do the dual in single outs..........
But if you are searching for original then go with a dasnk unit as thats all thats available except the ansa look alikes

The funny thing about concours winners is that they were NEVER ratty in the first place. You read about guys finding a pristine '67S in a barn, well, the one that wins the Manhattan trophy is the one owned by the Porsche Dealer from Ohio who never let it sit in a barn in the first place!
You can still find original steel heat exchangers from time to time. If a set can be obtained, I would have them jet-hot coated in ceramic the same color as the original Dove Gray. For while Mr. Gulick is accurate, that a sausage can be changed on the way to the parade ground, only the most stalwart street/concours enthusiasts have the courage to whip out the blue wrench to change their HE's!

Update- Installed the Dansk "stock" muffler over the weekend. Of course, the heat exchangers didn't line up, so I had to go through the whole loosening process. Took quite a bit of time but had no disaster with broken studs. In fact, everything came off ok once I had the right tools.
My original muffler is a Bischoff, and it has a 76 date stamp. Like John's, it's marked 3 years ahead of the car's vintage. Maybe it's like a freshness date? If so, mine lasted an extra 30 years... Anyway, the car is running well and the I'm not experiencing any of the dreaded mid-range flat spots. Thanks for everyone's input!
