I pulled the trigger on a set of SSI heat exchangers from SMC (with corresponding early 2.0 hanger bracket). Should be a nice upgrade from my stock 1975 exchangers with the combined outlets. So now I am in the hunt for a compatible 2.0 muffler (1974 and earlier).

I’m excited to be getting rid of the rusted 4 tip Monza muffler that came with the car and considering a few options.
1. Dansk factory replacement hotdog muffler. Possibly the quietest option and by some accounts the best performance since it is how the car was engineered by Porsche. However not stainless - although the car is fully garaged and typically driven in fair conditions so may be less of a concern. Sounded great in a video posted by user CCE from Mexico.
2. Mittlemotor. Not much more expensive than the Dansk at SMC and full stainless (and 15% off thru April 5th). Reviews here on the world were limited, but positive.
3. Would love to have gotten one of Ben’s mufflers. Looks like a similar product was available from 914rubber last year but no longer on the website. I have inquired about upcoming availability. As a side note, Ben seems to recommend factory replacement in recent threads on the topic which has me thinking about the factory Dansk…

Scart sounds nice but very expensive.

Would also consider the tangerine muffler made for heat exchangers if anyone has experience or a recommendation there. A little more spendy, but worth it for the value of the product in terms of quality and performance. I have not seen much on sound level or exhaust note on this.

Overall priorities:
Reduced noise level (compared to the Monza)
Factory or better performance
Nice exhaust note
Quality construction and value for the $$$

I really appreciate all the previous topics here on 914world that helped me understand the various heat exchangers and mufflers and figure out what was on my car and where to go next!

If you have a stock motor, I'd go with the Bursch or Dansk. Bursch for sound, and the Dansk for being as close to stock as you can get and being pretty quiet.

If you can find a Triad, they are also great and show up on the used market from time to time. Louder then the Dansk and easy to put an 02 sensor in if you go modern EFI. They look incredible, with two beefy pipes hanging out the back. Heavy and you need to paint them from time to time. Mine may be for sale.

Vintage Speed makes a nice stainless exhaust, but my understanding is that they are LOUD. If you want loud, this is an option.

Tangerine headers are the gold standard and can help wake up a modified engine. The heat exchanger is small.

I have one of Ben's and love it but its not quiet, its similar to the Triad but lighter.

OEM and Dansk for sale in classified section.

dansk

factory is the best one for reasonable quiet sound.
assuming the dansk is the same, but no personal experience.

triad gets very loud on the highway.
I went back to stock 2.0 muffler (used) so I could handle the drone on road trips

I was not a fan of the Triad. It was too loud for me, and it was pretty heavy.

If I have a teener that loud it better have a six in it.

I have both the Bursch and the Dansk and use stainless bolts so I can swap fast if I go into a show. The Bursch is not too loud and is much lighter than the Dansk.
