Stock exhaust size?

Can someone tell me what size the stock exhaust piping is for a 93 Z28? The search function is not working (keeps saying page cannot be displayed) and I am wanting to order a cutout today. Thanks in advance.

I don't know if they make 2.75" cutouts??

If they don't, I'm sure you could go 3" and have adapter pipe welded in, I would talk to an exhaust shop. The probably could slide the 3" cutout over your exhaust and weld a bead around.....

I've never seen a 2.75 inch cutout on the market. Most people just buy a 3" cutout and have an exhaust shop install it for a small fee.
