Dansk SS Euro Premuffler group buy

Wayne 962 · Wayne 962's Garage

Hi all. I have removed the original 4-page thread on this. Why? Here are just a few reasons, and a few mistakes people have made:

- My salesrep, whomever it was, should have been able to find this part. Whether or not it was because the wrong part number was given, or the wrong part number was listed in the system, the fact of the matter is that our supplier does indeed appear to carry this product.

- The part number from Dansk appears to be 92.100S, which is called a "Sport-CAT" not a pre-muffler as a bunch of you have been calling it. I'm sure both names are correct, but this has added to more confusion. The Sport-CAT is available with, or without the catalyst. The Euro Premuffler that you guys are referring to is the one without the catalyst. I specifically asked Tom yesterday if we carried a Euro Pre-muffler, to which he responded, "no, we only carry the Sport-CAT". I know am told that these are one and the same.

- Wavey (Dave Thomas) posted the information on the group buy without checking with me, or asking permission first. This was a no-no; one that he realized in hindsight. What he should have done was asked me about whether he could post it. Then I would have been able to research the issue a bit, and save everyone here loads of time and effort.

- Danskman (Mike Jensen) did not contact me (owner and operator of this BBS) about where to get this product, or even the correct part numbers. Instead, he was offering to arrange for you to purchase it through one of my competitors. This in my opinion is 'questionably unwise' behavior for a rep whose products I currently sell. I understand he was well intensioned, but he stepped on my foot in the process.

- I have added the Sport-CAT to the catalog (Euro Pre-muffler). Dansk Part number 92.100S. Pelican Parts part number PEL-99-1012-253 and PEL-99-1012-252 (catalyst version). The price for the Sport CAT without catalyst is $319, the price for the Sport CAT with catalyst is $899. I am uploading the new pages to the server right now, and in a short while, you should be able to find them on this page under catalytic converters:

http://www.pelicanparts.com/catalog/shopcart/911M/por_911M_exhaus_main.htm

You can also do a search for these part numbers, and they should show up in the database.

Contrary to what Danskman incorrectly stated in the original thread, these are currently *not* in stock with my supplier, and would need to be ordered. I would suspect that they could take from a few days to a few weeks to come in.

- Dave Thomas can be reached at davethomas@empowering.com if you wish to contact him regarding continuing the group buy. I don't want any more discussion of it here on this forum.

Wayne, thanks for this final clarification. I understand your need to delete the post. Thank you for doing your homework and adding the part to the Pelican catalog.

My only other response is that I consider calling Pelican and inquiring about the availability of the part, which both Clay and I did, to be an honest effort on our part. We were both told "No" in no uncertain terms by your employee, which indicated to us that Pelican had no interest in selling the part. I apologize if I should have then contacted you directly, but you and I will just have to disagree on this point.

That being said, I consider this to be a fair and gentlemanly resolution to the issue.

No, Dave you are 100% absolutely incorrect. Whether or not the part was available from us as a supplier or not, you should have CONTACTED me, and ASKED me FIRST, before you placed any group buy information on this BBS.

Period.

There is no disagreement on that point.

I think there's several good and strong points for both parties here. Mistakes in communication were obviously made on both ends, most if not all innocently and unknowingly. Let's let this rest as it is and move on.

Lesson learned for all involved.

Wayne, I understand this is your board, and I know you have become a bit hot under the collar about this, but maybe it is time to just let this one die. On the bright side I plan on ordering all the gaskets from you not to mention the lug nuts I now need for the wheels I bought, and a new o2 sensor. . .

Okay, Kurt, you're right - I'll go have some lunch now...

And those sure are nice wheels, Kurt!

Does the Dansk pre-silencer (99-1012-253) come with new gaskets (I assume there are gaskets at either end), and new bolts and nuts? If not, where would I get them? I recall that the previous thread said something about using stainless steel bolts (and nuts?). Would I be correct in thinking that I should expect problems in getting the old bolts off? I recently tried to remove a damaged bumper on my old Toyota pick-up and gave up because the bolts were so badly rusted and I succeeded only in rounding off the nuts.
I would be interested to hear, from people who actually have this pre-silencer installed, as to how much louder it is. I already have a second outlet on the stock muffler, so its alrerady a bit louder than stock Carrera.

VincentVega · 04-15-2003, 07:15 AM

I removed the cat on my SC and the bolts were indeed too rusted to removed with a socket/wrench. Out cam the wizzer wheel and they were off in 10 seconds. Whenever doing exhaust work I think you should expect to cut the bolts off and feel good if you dont.

Good luck!

Decolliber · 04-15-2003, 07:24 AM

Umm, ... what is a wizzer wheel? Is it a saw blade for cutting metal? I have a 7" metal cutter for my circular saw, but ... Maybe you mean a small cutting wheel for the end of a drill? If not, what do I look for at the hardware store?

VincentVega · 04-15-2003, 07:28 AM

Sorry, to me a wizzer wheel is one of these. A small hacksaw should work too, although space can be tight. Some guys swear by the dremel if you dont have air.

My 80SC bolts came off real easy, I think the original bronze (??) nuts were still on it and there was no corrosion whatsoever. I've done it on another car though were the bolts were stuck, they're a low grade bolt though and a good crank with the wrench will snap them off too.

Gaskets and bolts do not come with the new pipe. Order the gaskets through Pelican. The one triangle gasket is expensive, but you get what you pay for here, the cheap ones are just that....cheap.

As far as bolts go, I replaced mine with SAE stainless bolts and silicone bronze nuts....ie. no corrosion!!!
You can use metric stainless, but I haven't been able to find a source for the metric silicone/bronze nuts yet. Don't use stainless nuts, as they will gall on the SS bolts. Your local hardware store or marine shop should have these.

The Dansk Pre-Silencer should not add any volume to your exhaust, only increases exhaust flow. The baffles inside dampen the exhuast note just like the original cat does. I have the dual out Dansk Sport muffler and noticed no increase in volume by going to a "pre-muffler" over the cat.

Decolliber · 04-15-2003, 08:32 AM

Does the Dansk pre-silencer have a screw hole in the back for checking mixture, like the regular cat?

ckelly · 04-15-2003, 03:52 PM

No, I don't think so.

I'm not for sure, but I was under the impression that the screw hole was for testing backpressure of the converter so you could tell if it was becoming plugged or not. The O2 sensor should give you the mixture reading. Correct me if I'm wrong on this, but can't see why you'd need 2 points to check fuel/air ratios.

My understanding is that the most reliable way to set the mixture is to attach the exhaust gas analyser to the screw hole at the rear of the cat. It is possible to set mixture by checking the voltage across the terminals of the O2 sensor, but this seems to be unreliable. A mechanic who set my mixture that way left it much too rich, causing a surging idle. When I had my top end rebuild done, the mechanic (at Fisher Motors in Barrington, IL) set it by attaching the exhaust gas analyser to the cat.
If the pre-silencer does lack such an access point for an exhaust gas analyser, that would seem to pose a problem for setting mixture

If the pre-muffler/cat bypass has no cat you can check the CO2 just fine from the tail pipe.

Schuey · 04-15-2003, 06:00 PM

FYI: I did a search on the new area above on this PEL-99-1012-253 (did cut/paste) and came up with nothing...

Dansk Pre-Silencer / Euro Pre-Muffler, replaces stock 911 Catalytic Converter (1978-89), Dansk PN 92100S, polished stainless steel [Photo] [Photo]
PEL-99-1012-253 $319.00

Since the O2 sensor really is just a thermocouple and not a true gas or oxygen "analyzer", you would be correct that it is not a reliable source for a baseline mixture adjustment.

However, like Chris said, since the cat is no longer altering the exhuast gas for us (when using a pre-muffler), the tailpipe method works just as well if not the same.

Just to reiterate, the above statement would be absolutely correct.
