Header question

Looking to get a pair of Pacesetters for my 3.1l. I noticed on summit they do not list 3.1l headers so should I get the 2.8l or 3.4l headers?? I know both engines are similiar to mine but I don't want to buy them and have them not fit correctly.

they dont list 3.1 headers because they dont have any smog legal headers for the 3.1 engine. 2.8 headers will work fine, but you wont be able to pass a visual with them(no E.O. #). if you dont have to worry about visual smog checks, get the 2.8 headers. the 3.4s are made for the 4th gen chassis, dont get those ones.

No, the EGR will fit. They don't make headers for use with the air tubes, thats why they don't list them for the 3.1L.
