I have an 04 RalliArt, and Fiance has 02 OZ Rally. I was going to upgrade my exhaust and was wondering if my old exhaust could be used on her car, and if she would see any gains from it. (sound better, more ponies...). Please post if you have tried/thought about doing this.

Thanks.

Just to clarify, it would be the axle back portion I am swapping.
