Kartman01 Posted September 16, 2021 Share Posted September 16, 2021 I am seeking an OEM GM muffler for my 1950 Buick Super. GM part number is: 1331738. Specs are as follows: - 5" round - center in and center out - Body length - 43 1/4" long - Overall length - 47 1/4" - Inlet: 2" dia ID; outlet 2" dia ID Ideally item would be NOS original GM in box, but will consider good/used item. Not interested in IOC, Walker, AP, McCord, etc. aftermarket muffler. OEM units have internal disc baffle. Thanks in advance for any help Link to comment Share on other sites More sharing options...
