wow it's a slow weekend, can't believe you didn't get 10 repsonses telling you how stupid you are for not knowing that they use the same engine!!!! I imagine the only issue with the swaping of the engines would be the swapping of the computers too. Exhausts are definately different. If you do a search on "truebendz" you can get a look at how the 2 different setups look. You may be able to save some of the exhaust but I'm sure the way everything mounts up is different
