Nothing has been done as long as I have owned the car ... Monday it goes in the shop to get a look under it and see if there's anything to see as on now I looked under the car by laying on the ground and it all looks good ....

if they find a cat ripped open they have to replace it LOTS OF MONEY over $700.00,, if you know someone have them check it then buy one or two to fix it.
I was wondering if you have dumps on your car and they blow open then the elect switch will close them. either one will give you LOUD exhaust. jim

the cut outs /dumps could open when power is off if they are power closed... look for a switch ,also try every switch in the car, with engine running and see if the exhaust gets loud. ,, now you could look under the car for a valve,,valves on your exhaust pipes close to the engine. jim
