I installed a scott rods 3" system about 3 weeks ago. I dont know if its just my truck or not, but I found no improvement. There is absolutely no difference to the stock exhaust. There is a very small improvement to low down torque but apart from that I would almost say it was a waste of money. Maybe I did something wrong?? There is no improvement to fuel economy and certainly no more power.
Maybe I need to install a chip to get the most out of it? Maybe it just needs a tune?
