Depends if the exhaust is already on.. Which I'm guessing it's not.
If he's currently running SDs.. The flange exit is 2.5.. ZZP exhaust is 3" so if he's installing the exhaust himself guessing at home or such.. There's gonna be some downtime between him pulling off the SD downpipe to either have a 3" flange welded on so he can bolt Zzpoops exhaust on. Or just get the piece linked and cut off the 2.5 flange and some piping if needed and clamp it on. Bolt exhaust on then have it all welded if you like.
Yup I'm having to figure a solution out myself here soon.
