cat converter question

[dank24]

Alright I am just going to end up putting a cat converter back on my car. I have a Dia. of 2.5" , so what oem cat converter should I use? GSR? SI? I was thinking si but whats the stock Dia.? I don't want to get a high flow one because of the check engine light.

I got one of those Highflow cats off ebay, and it gave me a cel. So I need a stock one.
