GM Part No....
Can someone give me the GM part no. for the C5 exhaust pipe (actually, it's a double pipe) that runs from both cat converters to both muffler tail pipe connections. My car is a '98. Thank you....

I looked at a 97-02 Parts Manual and it showed an illustration of the Y pipe but no corresponding # or part #. It had info for the converters and info for the catbacks, but nothing for the pipe in between them.
EDIT
I went back and looked again and saw where the converter and Y pipe is one piece.
Part # 88896488
Part # 12458423

RocknRoll---thanks for your help. Found out what I needed to know----there is no section such as I'm looking for. You got to buy the whole unit. The flange on my left exhaust pipe spapped off, thus, my muffler is not stable and is dangling in the air. I now have an excuse to purchase a "X" pipe exhaust from Corsa or Borla. Thanks again for your help....
