I did mine last weekend - put on the Bassani-X. The rear was backed up onto some ramps and the front was supported on jackstands. I needed the extra room. F91 is right about the bolts on the front, with the heads on the top side it was a real PIA to get an open end wrench on it and there is not much room to turn it either, luckily once the were broke loose, they could be turned from the bottom with my fingers. When I reinstalled I reversed the clamp direction so I could bolt it on easier. Install time took about an hour and my wife was there to help lend a hand as she always does!
Next mod is getting rid of the crushed resonators!
