Default Re: Weld On vs Slip On Muffler Question

Yes ses light will be on if you don't put sims in place of rear sensors. This will make your truck run in open loop operation all the time meaning that it will run off a base fuel air mixture and the ecm will not control adjustments. This will affect performance and fuel mileage. Will run better with cats in place if you don't find sims for rear
