It sounds good but accelerating resonates terribly in the cab, which is good if your racing someone but after a week or so having them open I put them on so I can listen to the radio and talk on the phone while I drive. I would say go with the 3 bolt set up over electric it only takes me a few minutes to get both of them on and off.
