We're the stock mufflers painted black from the factory on a 1971 BB? Thanx.

Hi,
I believe the amount of black on the mufflers varied a bit from car to car.

The rear underside was just given a 'shot' of blackout spray to mask the reflective metal. The underside of the mufflers were included. The entire muffler was not painted black.

I'm glad you guys elaborated. I was actually hoping for that. Will be changing my exhaust soon and want to paint the mufflers before they go back in. Thanx every one.

So when did they stop painting the underside and exhaust on vettes? What year that is.

LT-1 kid

so why did you ask for only a yes or no answer.

I thought it's kind of a dumb question. Felt bad bugging people with it.

I would have to disagree on this.

While the mid year mufflers tended to be blacked out only on the bottom (most likely done at St. Louis), the later cars tended to have the entire muffler blacked out. This was probably done at the Walker (exhaust) plant as the part number labels are usually installed over the paint.

While I can't be certain at what location the paint was applied, I am certain that for most of the 1968-1972 production run, the mufflers were completely painted. Perhaps some early 1968 cars used the "bottom only" method from the previous year, but certainly by the start of the 1969 model year, the mufflers were all black.

To add the mufflers were hung on a rack system which on many left clues showing "runs" in the paint in a direction that couldn't have happened when installed under the car.

Hi,
This picture appears to be an example of the painting method WB describes.
It also appears to indicate how much paint could be on the muffler (and the pipes).
This is a sb 69.
Has it been 'massaged'???
Regards,
Alan

My guess would be 74 when the rear bumper cover was added. Honest answer would be when the bean counters told GM they could save a nickel per car if they quit doing it.
