Can someone help me identify this muffler? I could not find a part number on it. Reviewing pictures online, the 914-6, early 911, and even 912 look very similar. Are there measurements I can take to confirm? I don't have an assembled car to trial fit it on.
Did I mention it is hanging about 10 feet up on a wall with headers attached? Not certain if the headers are meant for the muffler. I can pull down if necessary.  |

Looks like the Leistritz muffler I have which has a 1969 date code...the one on the bottom....Leistritz and the Bischoff mufflers were factory installed....you can usually find a date code and model # stamped in on the bottom of the factory muffler....the 911 models tip have a downward and outward angle....the 914-6 model tip is more straight backward. You can see the the tip angle better on the 1972 Bischoff muffler on the top and the tip is a smooth pipe like most mufflers.

Thanks for your suggestion regarding date code and model. I took another pass and found this obscured by a lot of dust. 901.011.08/04 70 901/1 I guess this makes it a Leistritz for 911/12 from April 1970.  |
