Am I right from what the parts store says and its a 2.75" inlet, 2.5" outlet on the muffler? I picked up a thrush welded to replace my stock broken one, and then I'd need to get an adapter.

Thanks.

 

Anyone?
I'm talking about the pipe from the convertor being 2 3/4" diameter, and the tail pipe is 2 1/2". Can anyone verify this?

 

For the V6 and V8 models of the dakots they use a 2" pipe from manifold to Y.

then from Y to Muffler is 3" then 2 1/2" out the back behind the passenger side tire

also says 2.5 at cat and muffler.. and tailpipe is 2.5 as I just replaced mine

EDIT... PRE 94 were 3 inch ..
information from repair manual... assuming its still stock ...

 

92 and 93 were bigger. I have 92 manifolds on my engine and 2 1/2" pipe from the manifold all the way back to the end of the tail pipe. It slipped right on to the manifold
