I just bought a new muffler from Lang's and I swear it is louder than than the one I took off, that I had backfired the seams open on. When I look inside, it looks like there is a space at the end of the intake tube and the same when I look into the exit opening. Is there a way to check if this was assembled incorrectly or is there any way to quiet it down. This is one with the nut welded and the seams welded. No easy way to take it apart.
Model T mufflers are just three tubes held together by the end caps. The inner ones have large holes at one end of each tube. These were made to "muffle" the sound not be real quiet. Look at the diagram in the catalog of the parts.
Check with Lang's tomorrow morning for your answer
You don't suppose they welded it together like the catalog shows the individual tubes with all the holes on one end?
Ya, call Lang's. :-)
Can you grind the weld off of the nut and get it apart?
The muffler on my 18 is brand new (but 30 years old) and is so terribly quiet, I took a tube out so I could hear it at speed.
This question has kind of been asked before about loudness of a new muffler... Hmmm.
New mufflers are sometimes louder due to the lack of accumulated mouse nests...
Oops. The Lang's catalog shows the replacement shells with holes at the rear...but that isn't how its assembled.
The small inner shell holes end goes to the rear, the middle shell holes go to the front.
I have a welded muffler on the '27 and it sounds good, the welds are spot welds around the front and end head caps, would be a bit of trouble to open it up.
Dan, Thank you and you're right. That's not how they're assembled. :-)
Yet, things can happen occasionally in production welding/assembly...
That diagram is what I was thinking about when I was babbling. :-) Bummer about the welds.
No mouse nests in my muffler Adam. :-)
Sorry about the thread drift Douglas. I'll step aside.
I do hope you get it sorted. :-)
If you know anything about T's, they stopped using the inner shell around 1920. After that the exhaust pipe itself was used as the inner shell. The new mufflers are replacements only.
Thanks Larry. The one I blew up and re-assembled years back didn't have the inner or middle shell at all.
