Default Did large port magnum ex manifolds come on Grand Cherokees?

I'm thinking about buying a '93 Grand Cherokee with 5.2 Magnum. I know that the pickups with Magnum engines had higher-flowing exhaust manifolds for 1992 and 1993, is this true for the Grand Cherokees as well? Or did they only come with the smaller magnum manifolds even in 93?

As far as i know the change was to the tune of the engine regardless of body style, the size difference is pretty obvious large outlet is 2 1/8 or 2 1/4 small is around 2 don't quote me i'd have to go outside and measure for exact diameter.

That's what I was hoping, it sure would be nice because it would save a lot of time and money in exhaust mods for me if I end up buying it.

I have a left side Cherokee manifold from about 93/94 it is 2 1/8" outlet. But, it does Flo much better then a left side 68 to 70 340 exhaust manifold, I have ran string around the 2 of them to see which 1 is the most restrictive. The 340 1 on the left side is way more restrictive. .
