    73 S - muffler question....

    I have a Herst Leistritz muffler - stamped 'made in W. Germany and 03 84 (assume production date?) that came with my car. The exterior is very solid, but when tipped side to side there is slight evidence of small bits of loose particles (rust bits?) inside, but nothing that will shake loose and come out from the tailpipe or inlets. I am inclined to use it when I start the freshly rebuilt engine and then assess it further. Is anyone familiar with this brand of exhaust, i.e. was it a premium, mid-level or low-end replacement unit? Thank you.

    Leistritz was an OEM supplier for Porsche at that time. The muffler you have is an early style replacement stainless steel, good stuff. Yes a March 1984 build date, and should also say type 911.

    Thank you for the prompt and informative reply, and yes, it is stamped '911'. The previous owner had mentioned that it was stainless steel, but I was unsure with the discoloration/tarnishing in the vicinity of the header inlets. Thanks again!

    Remember that the final exhaust tube exits differently than on a 73 muffler. I only mention this since you are trying to be so precise in your restoration. You can always cut the exit tube off and replace.

    Thank you...had no idea. Is the exhaust pipe difference obvious, i.e. what should I look for/how to tell if what I have will work or simply wait until I get to installing the left side bumper and check the exhaust cut-out in the sheetmetal for clearance and fit?

    It has a curve down to clear the later bumpers. It will come out a bit lower than the 73 version and the chrome tip will not slide on due to the additional curve.
    You don't have to modify if you leave it without the chrome tip.
