Much better than Reviews!!!!
To help anyone on the fence, I decided to take the time to tell my story. I have a 2011 Toyota tundra crewmax 5.7 with a drop in K&N high performance filter.(Same results as a C.A.I. system but only 60.00!) Simply put,if you drive easy you WILL see a mpg increase!and in my experience at least 1-2 mpg getting on it alittle! The Reps. at autoanything were VERY kind and patient as I asked a lot of questions before my purchase! I got the catback straight out the back system with a s-type muffler.
