It depends on if it came with the optional SLP Dual Dual or not. What do the tips look like? One on each side or two on each side?

Here's the one you'll need, if you have the factory GM exhaust.

It's just one on each side and I don't think that muffler will work cuz I got 2 pipes going in and 2 coming out

The stock over axle pipe is 2.75" on regular Z28s; I'm not sure if there is any difference for the SS. The stock muffler is 3" in, 2.5" out - one in, two out.

The Magnaflow part number for stainless steel is 12267, 14267 polished ss. I got the non-polished for $100 shipped.

Why would it have 3 in in and 2.5 out if it's 2.75

I'm really not trying to be a smartass here, but instead of relying on someone else's information and possibly ordering the wrong parts, why don't you crawl under the car and measure the exhaust pipe diameter yourself.

So the pipes will fit into one another. For example, 2.75" into 3"

A quick search will tell you the same info.
