Best Exhaust sytem?

[5.0 Pony]

Im getting a new exhaust system this winter and im trying to decide which one to get. My car still has the stock system on it with the 4 catalytic converters. Those are coming off definitely, i know that there are sensors in the exhaust system, If i get an off road x-pipe/h pipe, how will it affect that sensor? Also, what exhaust sytem do u reccomend? Right now im thinking about the Flowmaster Quiet THunder CAt Back system, anyone running this? Any suggestions?

The flowmasters have a very nice sound to them. I am pretty sure you are referring to the flowmaster force 2 catback. If you get an off road h or x pipe, this may cause your check engine light to come on, however for approximently $30 you can by MIL eliminators to stop this from happening, and have no problems what so ever.
