Not sure what light he's referring to (maybe the Check Engine Light?) and what code it would throw but as long as your O2 sensors are put back in, you should have no problem with a series 40. What some folks forget it that you can't go too large on pipe size from front to back. If you are only replacing the muffler and have the stock pipes to the front and back, you won't lose any low end torque. At least you won't lose any such that you'd notice any loss.
