    "leistritz" is written (stamped) in script on my 1970's muffler...not the double line block style stamping shown in the pic...but mine is a stock two in one out stainless muffler. It may have been different with the "sport" mufflers?

    I don't know the history of my muffler. It came with the car when I bought it last december. The fellow I bought the car from had just purchased it.

    Just curiosity on this end...the number on mine is 6210783...and then "0975"...meaning made in sept. of '75? About right, since I bought it in '75, after a long trip with a 2 pipe gutted muffler convinced me I didn't want to go that way...

    I guess the 02 90 on mine would mean it was made in Feb. 1990 then.

    Is this a common way to mark Porsche parts?

    Wink part number

    They seem to be all a little different from each other...
    Mine doesn't have the big 'Leistritz' script, on mine it is a small square logo (about 20 by 20 millimeters tall), with a cursive 'Leistritz' font in the center. My part number is 901.011.080/0579... does that mean May of 1979???

    I don't know what I got but I sure like it!!!

    Looking at both my early mufflers (one original to my 67S and the other original to my 69E), I can not find a part number anywhere. I just had them both blasted/cleaned for a new finish and can see no numbers at all. Is this common?

    I was asked to show a pic of the caps on. They bolt up from between the pipes.
