The stock exhaust size is 2.25 inches.

A quick search would have easily found this information.

I did. But it seemed like all I was getting were threads about n/a. But thank you. I ask cause I had to order a megan downpipe and was told by the rep at extremepsi that it would fit my stock exhaust. But the downpipe has a 2.5 inlet and 2.5 outlet.

It will fit, since the flange holes are slotted. It's designed to be used in conjunction with the tubular O2 housing.

Ok, great. Thanks. I had them ship it to the shop that is doing my inspection and I was just unsure it would fit my stock exhaust. Thanks again.

I assume you are replacing the entire exhaust, correct? You do realize that most aftermarket downpipes are designed to be used without cats, and if a catalytic converter is required for emissions in your county you will most likely have to cut and weld a high flow in.
