Go to Napa Tell them what you have. I found part number: EXH 40439 for a total of $204.00 . Pick up the Y pipe from them and install it your self with some new gaskets.

blue iroc z28,
On Rockauto.com you can find the stock y pipes for around 125$.
If you use 3" cat converter, macperformance.com sells a nice one for around 170$. (the same one can be found at hawks)
