67 off road muffler blackout

[Hank H.]

Gentlemen, I have researched the archives regarding muffler blackout, but failed to see a thread regarding any differences between standard systems and the N11 off road mufflers for a C2. If the process includes blacking out the underside as stated in various posts, how does the "off road assembly" stamp interact? After blackout so it is visible, or are the bottoms of off road mufflers free of blackout? I am assuming that this stamp is a judged item, although I do not find a reference to it in the judging guide. By the way, the manual still states that the entire upper part of system is blacked out, not the underside?? Don't mean to beat a dead horse, but which way is it currently being judged? thanks

Hank,
Enclosed are two photos of a 5 Star Bowtie 1967 with the off road mufflers. This car had not been driven since about 1969. As you can see, not much evidence of black out.

Thanks Page. Seems pretty clear as far as the bottoms go. Do you see evidence of blackout on top of the mufflers on this car?

Page,

Is there a reason why a car optioned with Off-road exhaust would get treated differently when it went through the "blackout" station? Would it be a case of random application (some get very little like the car in your pictures, others get more), or were cars with N11 exhaust excluded from the muffler blackout process for some reason?

Is that the remains of some owner applied white paint?

Page,

And just to be clear, is there evidence of blackout anywhere on the mufflers? I don't really see any. Is there any on the rearward facing end?

Re: 67 off road muffler blackout

Here are a few more pictures of the same 1967. The first two photos are Gary Seymour's and the others are mine. These photos were taken before any cleaning was done to this car and before it went thru NCRS judging process and recieved all 5 Stars. The whitish areas are some type of corrosion that the camera magified. The only evidence of black out is in one of Gary's side views at the very top of the one of the mufflers. This is one of those cars you which you had taken all the photos that the camera would allow, but glad we got the ones we have. Love all the spider webs.

Thanks Page. Good pictures. It's very strange that there appears to be almost no chassis black on the bottoms of the mufflers.

Is this car from the midwest? Possibly Illinois or Wisconsin?

Re: 67 off road muffler blackout

My understanding is the car was purchased new in New York state and driven for a two or three years then parked until purchased in 2005. It's also a 427/435 convertible.

Ok, thanks. Not the same car I was thinking of. I thought it might be the green coupe that was at an NCRS events not too long ago.

Page, I'm trying to read the yellow characters on one of the mufflers. I can only read "OFF ROAD" but not the the following characters. Also is there a debossed "A" on both mufflers.

Was yellow paint/ink the original markings on original N11 off road system.

Great photos, thanks for posting them. I just installed a Gardner exhaust system on my 67 and trying to decide if I should put part #'s and date on them.

Ron -

The yellow stencil reads "Off Road Assembly"; it was the only way of identifying the original production-line N-11 muffler assemblies at St. Louis, as they didn't have part numbers embossed on the muffler. The "A" embossment is for Arvin (Walker made all the other mufflers).
