Default Cat and Y with stock manifolds

I have a 98 z28 with ported 2002 manifolds and a 2002 y-pipe. I am going for the sleeper effect, so I want to keep my ported manifolds.

1.What y-pipes will bolt up to the stock manifolds and which are the "best" in your opinion?

2.Which y-pipes come with cats? and What kind of cats?

3.Random Tech or Magna flow cats?? Where can I get them cheap?

I ran the Random Tech Y (w/cats) for a while on my ported manifolds. Picked up ~7hp with the combo. It was a little expensive for the minimal gains. You might consider just sticking with the stock Y.

I went from 330hp to 337hp after installing the ported stockers and Random Tech Y. Same Dyno, different day.
