Thanks!

You can call me crazy but those look like the 917/30 exhaust extensions.

No heaterboxes.. so for racing only

Those appear to be very similar to the factory supplied header/megaphone setup on early 911 ST racers. I can't find pictures right now, but that might be your answer.

They appear to be on a 2.7 RS...(clone?)

Now that my curiosity has been piqued, what exactly are those for?

To actually answer your question...

This is the muffler used to match up with factory tubular exhaust headers or "spagetis" and short megaphones or "diffusoren."

This style muffler was used in 1970, 71 and 72 on 911ST and 914-6GT and later the 2.8 RSR.

(BTW, this explanation came from a post on Early911SRegistry.org)

Oh so they're actually just a long muffler and not what looks to be a funnel around a straight pipe?

well... Its more similar to the latter than the former, but I suppose you could call them mufflers.

See now i'm wondering which car i have would actually look good with those.

I have "standard" headers on my car (there seems to lots of variations, but they pull back more then the Clarks Ultimates, more like the pic above). I bought them from a Corvair shop, not sure who would make them now, probably best to look around Corvair boards etc. They seem to come up for sale occasionally.

My headers did get destroyed on one side after an accident and I had to repair them. Finding the right tubing size (2 1/4 I think) is pretty hard, but it is out there.

I run them into a pair of Dynamax Super Turbo mufflers. They make a nice sound. One important note: make sure to run a longish tailpipe out the the rear, without it the resonation (around 2800 rpm) is insane! I could feel the pressure waves in my ear while driving with the windows down. Put 6 inches of pipe off the end, much nicer.

I have a 2.9 liter (VW piston cylinders) with modified heads for 9.5:1 CR. Makes a nice crisp sound with the headers, not obnoxious though.

Try these guys, they should be able to get you what you need:

Megaphones are pretty commonly available if you're doing a custom fabbed setup. I like the Burns Stainless parts the most when I daydream about my next set. My first car was my baja Bug that had a "stinger" so I've always had a soft spot for them. Loud, no doubt, and when you're doing things wrong like exhaust leaks and overly rich fuel conditions, you get awesome flames out of them.

Flames is what I'm aiming for! Lots of guys used to run stingers on Corvairs which I also love...but it's just another thing to fabricate ... I want that classic racer feel...

They wouldn't be that hard to fab up, but if you want pre-fabbed they're out there. I did some googling and found the Porsche guys call them "cookie cutter" megaphones:

Under $200 for a set pre-fabbed if you're down with mild steel.
