Dual CAT Exhaust Question
I have the Dual Cats on my 89 Formula and was wondering if is cat back pipe the is same for dual cats as the single? Can't find any information. Just want to keep it stock but get a Magnaflow or Flowmaster exhasut on it. 2.5 is fine for street car unless we get me some good part numbers as I want to hang it myself.

No, they do not use the same intermediate pipe.
The stock catback is 2 3/4 inches if you have the dual kit. Most good catbacks will be 3" or bigger.
