I have a pair of oem -442 tailpipes with the chrome tips for sale that came out of an old Olds dealer that went out of business , i don"t think it will affect the operation of it . Look at the pictures and see what you think . The part numbers are 402541 and 402540 , # 402541 is dented . The tips are coated with something from the factory , they would have to be chrome polished to get them to shine . Prefer pick up in Hebron Illinois , shipping could be expensive for the buyer from zip 60034 . Asking $250 plus shipping . Theses pipes have been sold .

They will probably fit 68-72 if you want to expand your sales range. Did not know you could order them from the factory with tips installed. Maybe these were a return. Any evidence of use? That dent looks kind of nasty - probably worth cutting out and replacing as it will restrict flow at that location. Good luck with the sale!

Yep, you could get the pipes with the tips already welded on from GM. I don't know if they were always available like that. The local Olds dealer simply gave me a brand new one a long time ago with a bunch of other "old" Olds parts when they were cleaning out their stuff in the back when they moved to a new building. It's got surface rust on it with the GM number band still on it. The chrome on the tip isn't great, but kept it anyway because I thought it was cool.

Bob- can't see very good detail, but do these have chambered rear sections?

We had a local parts store here that carried one lh and one rh 442 exhaust with the tips welded on...when they sold one, they reordered one.

They came with tips.
Not so sure about the '68-'72 fit.
The 1972 Parts Book shows the 402540/402541 as 1968 only. 402710/402711 for 1969 only, and 404664/404665 for '70-'72.

No , the ends at the tips are not chambered . Pictures did not turn out as planned , i will take some more and post . thanks BOB

If in fact these tips were welded from the factory then it would be great if you could take some measurements of exactly where the trumpet is. Many have asked for this info and this would be a great bit of info for all. Many cars dont have the correct distance from the bumper to trumpet.

sicky olds

agreed!!!!

While an interesting thought, not sure if it would make much difference than lining them up and doing it yourself. reason I say that is that some instances had factory tips very close to the bumper at assembly, but some people prefer a little more space. I think the sweet spot was for the trumpet flare to start just under the cutout, but not sure on that.

That's not really going to tell you anything. There are 2 things one needs for locating the tip properly:
1. the distance from the bumper "up and down"
2. the front to back location.
Any measurement of the pipe will tell you nothing about #1, and #2 has a variable of how far the pipe is on the muffler, let alone coming up with any measurement that would do you any good.
Its one of those things that sounds like a good idea, but really isn't.
There is, however, some guidance in the Assembly Manuals. 1968 does not show anything, but the '69-up ones do. There is a specific dimension given for #1, and from the illustration, you can pretty well determine #2.

And I'll again point out that these Assembly Manuals are available free of charge on Wild About Cars.

Kurt, is there ANYTHING Oldsmobile that you don't know?

But I agree, depending on your bumper location, that would also determine how you would need to adjust the pipe tip. Very rarely do two bumpers match exactly in their fore/aft and up/down positions.

I took some measurements of where the tip was in relation to the end of the pipe and they were different . The drivers side i have has the tip farther away from the end of the pipe versus the passenger side was slide farther on the pipe . The tips are electrically spot welded to the pipe , obviously the assembly line just pushed them on and welded them at wherever they ended up . The tips are coated with some sort of protective material , used a little chrome polish on the drivers side and it comes off and the chrome is good . I will post some pictures of the measurement . I posted the pictures with the measurements on the original post . BOB

Glenn, I checked the Dec '68 Part Book and sure enough it has different numbers (399548/399549) for the '68 pipes. That does suggest that not only did the OE have chambered pipes, but possibly the early replacements were chambered too. Before they decided to entirely give up on the chambered pipes.

I thought everyone would have figured it out by now. I don't know anything. I just look it all up!
And now everyone can look it up on WILD ABOUT CARS!!

These are not chambered . Wish they were . Sorry for the quality of the pictures . BOB

HERE IS A COLOR SHOT OF THE 68 SHOWCAR. CHECK OUT THE RED INNER PIPES.
NOT TO MENTION THE RED BOOTS.

The book "Oldsmobile The Performance Years"(Martyn Schorr-formerly of Cars Magazine) has some illustrations on the 67 442 boasting chambered pipes for a special exhaust note; However, this may be completely irrevelant if you are discussing 68-72 tips.

In the '68 in those photos, what is that emblem? just fwd of the rear side marker light?? Not a production item.

Here is a chambered pipe, no clue what this one's PN is [should be 399548 and -9 I believe]

Sir, I will be in your area next week and have a '68 that could use these. I am cash poor, but parts rich. Do you need cylinder heads? Anything I could trade?

Wonder if anyone could find out the cutoff for use of chambered pipes in 68? and if they could, reckon Walt V would consider a run of them? If he's not interested, maybe Sweet-Thunder could duplicate them to where they could be used on 68-72.

I'll admit, I like both the look and the sound of them, and Olds being the first to use them as standard equipment on a production car should make any Oldsmobilist proud of them. Corvette with sidepipes and Mustang with Arvinode systems were extra cost options- 64 Starfire/Jetstar I had them standard.

I have an idea that Olds got wind that a few states were proposing banning any and all chambered exhaust systems due to the noise Chevrolets equipped with them made, so that may be why they were discontinued during 68 production. Vajenya still has that idiot 1969 law on the books, but I put the chambers on the green Starfire anyway.

I think it may be a 442 emblem. This is a show car with several special items. I think the car was 455 powered. I believe the car still exist and is owned by a former Olds dealer in the south. It was in Muscle Car Review a few years back with some other Oldsmobiles.
