necking down after collecter?

Sounded like crap to me too. I'm looking for 3" extension/collectors, Summit does not have a 3" in 3" out. Not that I can find.

Like this?

You can also get 3" "reducers" made for a 3" collector that are made to weld the rest of your exhaust to. Either way works. The torsion bar cross member is typically pretty close though... So the longer extensions may be more trouble.
