 I posted back on 4/30/06 and I wanted to comment again.  I've owned my Tundra 2 1/2 years now and I'm totally satisfied.  I did put flowmasters 70 series (duals) on it and I'm very pleased.  Additionally, I did put a K&N filter in it as well.  I like the sound of it but more importantly my MPG is decent now.  I don't drive like a race car driver but I do use it like a truck.  City driving I get 16-17.  Highway is 19 to 22.  Here is the secret... 70 MPH is where I stop getting 20 MPG or better.  It drops down to 18-19 MPG.
