We have vibrations in the floor of the RV9A and I assume they are from the Horizontal Exhaust pipes. When feet on pedals: no vibration, with feet on floor: feels like feet going to sleep. (pins & needles) Assuming its from the high speed palpitations of the horizontal exhaust outlets patting against the belly. Does anyone offer 45 degree tips or sleeves that can be easily added without dismantling exhaust system? Anyone else have these symptom's? Ed S.
