I put this on my 07 Tundra 5.7. Over all in pretty happy with it. I have noticed a slight increase of mpg's of just around 1. installation was a bit tricky due to the poor quality of pictures but I still got it done in about an hour.
Product is worth it

First off I honestly have saved gas by using this product. Its not as loud as I expected. I really can't hear any difference but the performance has improved as far as response to my acceleration. I am overall happy with my purchase and would recommend this.
