'04 Overland...wrong exhaust?

So I just picked up an '04 Overland (been wanting one for a looooong time)

The dealer needed to do some work on it, new brakes, rotors and exhaust.

Well....they replaced the exhaust with 2" pipe...I'm very concerned about this, but don't know enough to be sure.

So please, I need your advice.

Do I need to get the exhaust switched to 2.5"? Are there going to be issues with having a 2" exhaust?

Thanks for your help

I do believe the stock exhaust is 2.5"..... 2" seems a little small for a healthy V-8.

So they reduced it down after the y-pipe?

It looks like it's 2.5" going into the cat and 2" coming out.
I live in Vermont and since mufflers can rust out pretty quickly, I'm planning on replacing this spring with a full (or mostly) stainless exhaust system. I'm going to look into the system from Kopak (sp?) here on Jeepforum.
So my biggest concern is whether running it this winter and early spring with a 2" will hurt the vehicle in any way long term. Not worried if I can't do 0-60 in the snow.
Thanks

IMO you won't hurt anything long term the way it is.

All v8's are 2.5 all the way out. 4.0's are 2.5 to the cat then 2.25 the rest of the way. Having the 2" may or may not cause issues I would take it back immediately and say wtf because you WILL not have as much power as orignally with the 2.5". There is a difference I know for a fact I have a 4.0 and grabbed a overland stock 2.5" exhuast swapped into myn and I have alot more power and better sound. 2" is for a car not a suv.
