The kit gave me noticeable power increase from the midrange to top end. It also gave the engine a much more throaty sound under the Hood. I haven't had a chance to see if there were any MPG gains. The installation was fairly easy if you're patient. Looks better under the Hood then the stock system but not that spectacular.
