Yep, put on a Jardine system two weeks ago. First class components and easy install. Almost fell through the muffler while looking at it! Nice sound and a definite improvement in mileage and throttle response. The system was on the truck for about an eighth of a tank of fuel, and that tank's mileage went up 0. 75 MPG. I suspect that a full tank will be even better. Good stuff!
