ok so i have a question .. last night i went to the track in my rsx-s and afterwards i noticed my exhaust was a little louder and there was alot of vibrating coming from under the floorboard.. and i looked at all the bolts and they were tight and its still vibrating loud kind of like an exhaust leak... and i dont know if it could be in the motor itself or if it is deffinately the exhaust. please any feedback would be greatly appreciated..
