Im not sure either.. But I do have one sitting here in the box, from my dads rhino, it never got put on before he sold it. He would probably get rid of it pretty cheap if anyone is interested. its for a 700fi.
don't buy the gibson there exhaust is junk unless you want to be slower and louder than stock and have customer service that is less then nothing
sorry for the sale block but it the truth.
I wouldnt buy Gibson exhaust for nothing what do they know about building exhaust for a rhino. NOTHING.. I would stick with the people who know what there doing.
I can only speak for my one experience with a Gibson on a Rhino. It was fairly quite, but was terrible for power output. The Rhino i'm speaking of now has a Ron Woods exhaust and runs circles around the old setup. The Gibsons also seem to contribute to more frequently broken exhaust studs.
