BillOHIO, My 07 ST has the same dome light issue when I hit a bump or brake hard going down a hill. I doesn't do it all the time and I only notice it at night. It doesn't seem to be the doors, I can wiggle them and the light will NOT come on. If you discover the answer to this issue please post...
I have a 07 with a Magnaflow that sounds real nice when you get on it but does not have an irritating drone on the freeway. Also removed the resonator.
Use Tri Flow it is the best. Do NOT use WD-40 on anything you want to lubricate, it is a solvent and will remove any existing lubricant making it worse.
I have a Viper system on my ST. It is the second vehicle I have had with a Viper system.
It has been easy to use and trouble free. There also seems to be plenty of local techs who sell
and service the Viper systems.
