Going by the Flowmaster book, the 942551 and 942552 are both 2.5" IN/OUT
50-Series "Delta-Flow" mufflers. It's just a different offset on the
inlet and outlet for the part numbers. Both are more than adequate for
your truck.
I'm wondering if they installed it backwards as well - could be a
defective muffler (wouldn't rule that out either).

Subject: Re: DML: Flowmaster installed
This was immediately after I had installed the
Flowmaster onto my Dakota. Do I assume here that
somehow I got a defective muffler ??? I have not yet
tried putting on my old muffler yet...
Is that something I should try first ???
Any help will be appreciated......
