OEM 1969 sidepipes

Are these stamped with a part number from GM?

Re: OEM 1969 sidepipes

I just purchased a 427 set of 70's made Walker NOS pipes.
Other than the GM parts sticker, I did not see a stamped part number.

There are spot welds that go around the muffler section, somewhere about mid way.
There is a "W" stamped on the mounting tab at the rear by the exit down spout.
The 2" extension pipe is welded to the muffler section and the 2-1/2" area (for manifold) is welded to the 2" pipe.

I have set of NOS sidepipes on my 69 big block and they have the part numbers stamped on the pipes just ahead of the "muffler" assembly.

Thanks for that

Re: OEM 1969 sidepipes

i went back a checked on the pipes - can't find a stamped number, but maybe mine are a later Walker run.

I always heard the Walker pipes that were left over from production and put back into OTC stock had stamped numbers in them.

This was my craigslist find of the decade. These are the NOS pipes that I put on my 69 427 last year. Were likely over the counter pipes.
They have a small stamped set of numbers that I still havent been able to ID. They sounded super quiet at first but now have a nice low note.

Picked up a pair of NOS pipes in Canada. Shipping was a mess, anyway the exhaust are really nice. The do have a part number stamped on the pipes. Hope the pictures help. Steve104_2628.JPG104_2634-001.JPG

Here are pictures of the numbers stamped on the pipes on my car. Sorry for the bad quality - best I could do since they are on the car.sidepipe.jpgsidepipe2.jpg

Re: OEM 1969 sidepipes

The reason I bought these pipes had nothing to really do with being correct...was more for the sound. I had an original on my drivers side and am aftermarket on passenger so had two different sounds driving me crazy. I know that the pipe I took off was original. There were no part numbers anywhere.
