Fast Intentions exhaust is here!

Hey Tony, I've had my exhaust on for about 2 months now and I have a few questions. I got my system intalled at my local Midas and they really seem to know what their doing. I say this because I have gotten to know them over the past few months and they have all the answers. My point is that when I originaly got it installed, they used paper gaskets to seal it instead of the high temperature silicon that is said to be used in the instructions. It was installed succesfully and all was well for the first few weeks. After that I began hearing a hissing sound when I let off the gas and as the car slowed down. It sounded like a leakage but I wasn't sure so I left it for a week or so. About this time my "service engine soon" light came on. I took it into the dealership yesterday and they told me I had a blown front gasket that was throwing the cars sensors off. Knowing this I immediately took it to Midas and they confirmed this. They then proceeded to reseal it with the high temperature silicon. We followed the instructions on the package completely. Even letting it sit 2 hours before tightening the bolts. Yet, as I drove away I could hear the same old hissing. I have not confirmed that the gasket has blown again but I would guess it is. I am not positive if it was just the front gasket that was blown but I believe that was the only one. My question is a simple "what should I do?". I could look into getting metal gaskets to seal it but I was just wondering what you thought on the situation. Thanks P.S. I had them check for any other sources of leakage and they did not see any. Thanks again.
