To determine an exact amount of power gains for a 2014 Chevy Silverado 1500 with the 5.3 liter motor it would have to be placed on a Dyno to calculate its new output. When you add performance products to a vehicle, the gains do not necessarily stack. What I mean is if new exhaust adds 10 horsepower and a programmer adds 20 that doesn't mean that you added 30 horsepower; only that you increased it by up to 30 but its likely less.

So we can provide a ball park figure but putting the vehicle on a Dyno would be best.

The Edge Evolution, # EP39YR, claims up to 18 horsepower and 27 feet pounds of torque, cold air intake # EP284141-D estimates up to 14 additional horsepower, MagnaFlow exhaust seems to average around 10 or so additional horsepower. So, you are looking at up to about 45 more horsepower but would probably be less.

For the exhaust the options depend on the cab style and bed length so I have included a link to the exhaust main page for the vehicle. Just select the cab and bed style in the 5.3 liter motor options to see the exhaust systems that will fit that version of the truck.
