    Default Flowmaster 44 part number?

    Ive searched a million threads and cant really determine what muffler I would need to replace the stock one. Im not really sure what size inlet and outlet, is it a center in and out or offset will work? Any help would be greatly appreciated! Thanks in advance guys.

    As I recall, the Flowmaster 44 is a "toned down" version of the 40 series. You can still get the 40 series mufflers on ebay for $50 or so.
