If you look at your air inlet tube,You can remove the silencer,Do the freeze plug block off of the holes that I did to mine,See it in the archives,And that would give you a perfect place to mount the Nitrous/Fuel nozzle so no permanent mods are required.I would say if something happened and you took it off and went to the dealer you might be OK on this one.You don't even have to flash a tune as the ZEX nitrous system will handle the additional fuel required.
