Wanted images of 240 red block muffler's internals.

I came across this see through image in a file called 1981-244.pdf in the OZ archives:

1981 Volvo Muffler see through image.
Looks like a "S" exhaust path with cross flow.

EDIT:I made an effort to use Art's tutorial to post your image here but failed (twice). I don't know what I am doing wrong. The image below was posted here following those instructions.

Hi,

Which muffler are you wanting to see the guts of.

I have a rear one that I was going to recycle that’s all flaky on the inside as I can the crunchy sounds when I roll it. The outside was solid but I have seen split too
The inlet pipe rusted thin enough on the inside that about three inches of it pulled out of the whole thing.
I will have to look to see if it is Volvo or a NAPA or a Starla. I have experience with all but they seem all the same.

NAPA was weary of my last time replacing it under a lifetime warranty but they did it after I tell them I have the paperwork work. I have two cars with them but I’m having trouble remembering which car has it.

I have hurt them plenty but I gave up hurting J.C. PENNY for their first lifetime maintenance free batteries for my 1974 Ford Pickup. I thought three times was enough to call it even.😊

I do not drive as much as I use to either so the years are way past the normal failure rate and they are probably thinking … Is this guy really serious but they haven’t tried to say it’s lifetime is now obsolete.
Maybe because batteries and mufflers must be about as expendable as are the whole car today.

Volvo used to advertise that the 240 would outlast their bank payment cards and break the seven year cycle. But their mufflers never made it.
Their bumper to bumper transferable 36,000 mile warranties was hit by a mufflers.
I know as I clopped them out of only one.
🥳

Thanks for responding. I'm interested in seeing how a stock 240 1981 B21F muffler is layout inside and particularly the inlet and outlet connections. The example doesn't need to be in good condition just undamaged. Rust is ok.

I've thought of cutting one open at a junk yard and taking pictures but I'm in San Francisco and the closest yard is an hour and a half away if they even have a 240.

Hi John,

Well it just so happens I have that rear muffler in the back of my wagon that is headed North from my southern house
I was going to take it to WINSLOW Ca. to the JY or pick-n-pull there. They seem to have more 240s there than in Richmond Ca.
They like instant automotive scrap metal to sell to their contacts.

I going through S.F today in about 5hours plus depending on some traffic variables of course. 😬
I see an address in your profile that’s south of where I cross the golden gate.
I go up the 280 to highway ONE and not through downtown S.F. on the 101. It stays congested not that 19th isn’t.
I would have to back track only a few miles as MAPS shows me and you are in a complex of some sort.
Do you have shop or a home style garage to do what ever you are planning?
S.F. Is very urban is why I’m asking.

I can drop it off if you have a way to cut it open.
How are you going to do that in a JY with only battery operated tools allowed.
I have never cut one of these open. I think I would want a die grinder with an abrasive cut off wheel to slice it.

With that said … and Luck be having it, I have another one up farther north in my shop, that I need to dispose. I could cut it open before scraping it locally there.

So how badly do want to see inside?

Do You want photos or a hands on experience with dimensions?
Sometimes a reference scale laid in a photo can work.
If I have time during my house maintenance visit I can try to do that the other one.
My place locally up there doesn’t really like automotive parts but cutting it up helps disguise it some what.🥴
Haven’t figured out a way to do struts so on my way back south I try the JY but sometimes they close before I can get there. I live six hours north of that JY I mentioned.


So what you say, are you interested?

It's my understanding that in the two "muffler" system for non-turbo 240's--only one is actually a muffler--the other being a resonator. On my '93 245 Oldsmobile aluminum V8 conversion I used the single rear muffler of the Turbo models. It resulted in a nice throaty sound but not too loud. = Dave

I'm interested in the rear muffler just to be clear. Oh yes, I had an uncle who owned an Oldsmobile Cutlass with that engine back when they were small cars. When he passed I was offered the car. This was in the '70s when hi-octane gas became unavailable and the engine had a 10+ compression ratio so I passed.

Wow, golden opportunity! I may be late here for your trip north and I don't have a garage. I don't need anything precise so just pictures would be great.
