Re: duplicate the W on mufflers

I've heard of people making one from epoxy and then gluing it to the muffler.

Note that as a chassis judge if the rest of your system doesn't appear factory I won't be fooled by a W.

Who would consider such a nefarious deed?

That's a rhetorical question. Don't answer.

Never trust airline pilots. They spend their days breaking stuff.

Re: duplicate the W on mufflers

Are the W mufflers dated? I have a pair and they are embossed as follows: GM
3943386

W - 11 - 85

Thanks.

Folks feeling the need to re-create the "W" on a muffler shell are taking restoration to the level of a religion. I, for one, do not take restoration to the level of religion for practical purposes. I might enter into discussion of such levels of original detail, but I would never participate in such a "restoration" effort.

In the case of mufflers, I believe that trying to create every nuance of original detail of PRODUCTION mufflers while using GM SERVICE mufflers is wasted effort anyway. There are too many other differences, especially with respect to embossments, between PRODUCTION and SERVICE mufflers to allow one to "re-create" a PRODUCTION muffler using a SERVICE piece. As far as reproduction exhaust systems go, I don't think that anyone out there has a reproduction so accurate that one needs to start being concerned about adding a "W" embossment.

What about Gardner Exhaust Systems ??
will that be the most authentic reproduction exhaust system on the market ??

Re: duplicate the W on mufflers

The PRODUCTION early C3 mufflers are NOT dated and contain no embossments except the letter W = Walker, the manufacturer. SERVICE replacements of the same era were exact duplicates (including the W and the black-out) of the PRODUCTION muffler EXCEPT they did not have the attached inlet pipe and the hex-shaped locating tab for the 1970-1972 extension (commonly referred to as the "tip").

LATER C3 SERVICE mufflers mufflerws are as indicated by Michale M -- and of course the 1985 date would verify that. My best guess would be that may be the last batch of GM mufflers made for SERVICE for the C3's. Those may even be for the 1973 and > Corvettes which have a different outlet pipe configuration than earlier examples.

Jean-Francois we will have to know more about this muffler to determine if it would work for a 1969 or not.

Re: duplicate the W on mufflers

Watch it, ya dopes. My NOS sidepipes already had the W on the mounting flange, sooooo, I didn't have to bother with such a trivial thing.

Excuse me, I must get back to my maintenance logbook write ups. 

You might recite your squawk list to the ATC guys on one of your night flights to keep them awake .

Re: duplicate the W on mufflers

I know what the write-up's are:

1. Captains Seat Bottom Cushion is to thin.
2. Captains Coffee Cup Holder is broken.
3. Captains personal headset does not work on this A/C.

Sign-offs by Maintenance:

1. Captains cushion replace 2 flight legs ago all normal.
2. Found Captains coffee cup holder on cockpit floor reinstalled same all normal
3. Checked Captains headset jack with standard David Clark headset on VHF, UHF, HF, Intercom, PA, ADF, DME and side tone all checks normal.

But is it a real deal side pipe car? We may have issues here.

Frank,
You may want to exercise caution when creating an "identifier" on a part it was not originally on. In the judging reference manual on page 23 it calls out counterfeit identifiers as a no - no.

Specific examples are vin tags, trim tags, and castings but it does not say limited to these. Modifying the casting numbers on a master cylinder if detected may be considered counterfeit. Page 23 does not limit identifiers to only engine castings as it is stated. The only place that says stamping identification is ok is on page 11 is on the block.
