The TBS was so easy to install!! I dont even hear the "whine" that others have said they hear. I have a K&N system and dual Flowmaster exhaust so as far as gaining any MPG, hard to say which one of the 3 has contributed the most to my 5 mpg gain. Now a days you gotta do what you can to squeeze the most out of a gallon.
