Well, heres a follow up on my exhaust system... . It has KILLED my fuel mileage!!!. . Thats right, almost 5 MPG!!!!!. . I have checked and rechecked it!!. I am really at a loss as to what went wrong, All I did was remove some pipe, and installed some much prettier pipe, and BAM loss 5 MPG!.
Ok, with that being said, heres how I lost it. The dang truck sounds so good at 72 mph, but it REALLY sounds good at about 85 mph pulling a hill!!!. . And in town, if you keep the boost down at about 5 psi leaving a red-light it sounds good, but if you leave a red light at about 15 psi it sounds SOOO good that I just can't stop... If fuel was still $4. 35 a gallon, my ears would be writing checks that my wallet couldn't cash!!!...
