To resurrect this thread and ask another question….Has anyone retrofitted back to OEM from the SC? Two years ago I posted about my noisy SC and decided to bare with the noise. Well this past run from MA to VT changed that. Too damn noisy for me. So I seem to have the choice of taking the SC off and sending to FL for a rebuild (if the guy Dragon Bob mentioned earlier is still in business) and not have a vehicle during the down time or have engine returned to OEM and live with out it. So I’m opening this up to the list. What would you do? Also, if anyone is aware of a company that rebuilds Alpine SC please let me know. Thanks
