Put my order for the Kartboy exhaust hangers in on Sunday. They came today. Only got to install the rear hangers (due to lack of light), but I can already tell how much more stable it makes the exhaust. for the past couple weeks, my exhaust would sometimes rest on the axle and would rattle on it when i was in idle, but only after hard driving. i think this was because the high temps of the exhaust loosened the OEM hangers therefore "lowering" the exhaust on the axle. Im very impressed with the hangers and how much better they keep the exhaust in place. the best thing about my whole experience was the Twizzler included in the packaging!!!
