I think there is a difference between the Jetfire and non-Jetfires in that the muffler for the Jetfire is parallel to the axle, just in front of the gas tank and the exhaust pipe has to bend 90 degrees for that reason. Thanks for all of the info. P.S., I dont see a car registered un der “Hotwire” yet. If you would do that and send a picture, we would like to have your car included in our National Car Registery. Thanks again!
