Thread: Can this Leistritz be saved?

  1. #1

    Can this Leistritz be saved?

    Have the engine out for a gearbox swap and noticed the muffler has really started to go downhill. It was stored for many years and is rusting from the inside out. 1969 date code. No dents, un-scraped square tip. Kind of nice other than the rust. Several years ago when I got it, it was just a few of pinholes which I filled with muffler cement (no, I didn't expect it to last).

    Hate to throw it out -- can a metal guy cut this open and patch the rot? The new Dansk repops sound awful.

    IMO, it's done for. Just like rust anywhere else on a car, what you see on the outside is just the tip of the iceberg. Probably not a lot left inside other than rust.

    Years ago, back when I lived in California, there was a guy in Torrance who specialized in repairing mufflers for vintage cars. Mostly Ferraris to my recollection. Gary something. Or Greg. Good guy. That doesn't answer your question other to say that muffler repair is certainly a thing. Now you just gotta hope someone is doing it in today's throw-away world.

    What's left of that muffler is tissue paper and is almost impossible to save...

    However, cut the off your early exit right at the canister and keep it. You might run into someone selling a first generation mid-year muffler (74-76) in good shape, and all you have to do is cut off the 'crooked' exit off the mid-year and weld your early exit on and you've got and 'newer' early muffler.... Like I did..

    Hope this helps,

    Hardly. I'll look forward to your edit the next time someone makes a fun of Texas or Oklahoma.


    Ridiculous.

    Gene Smythe was the guy in Torrance repairing vintage mufflers back in the early 90's. Quick Google search shows nothing but maybe someone here will remember or know if he's still in business.

    This is why I rarely if ever sell used mufflers, they normally rust from the inside so even when they look ok from the outside the insides are almost always toast. People are never happy when they get one, so now I just say no.

    I hear that....

    Years ago I paid $200 to a local guy for a muffler that looked OK on the outside and turned out worse then the one it replaced...

    Hopefully I've learned...

    I bought it for a couple hundred bucks back in 2014 knowing it had a dozen pinholes, so I knew what I was getting into. Wish it could be saved. How hard could it be -- zip open the hot dog with a cutoff wheel, deal with the rust, and weld it closed? I can't stand the sound of the Dansks, they are loud and tinny, I like quiet and mellow.
