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.
