Earlier in the week, we mentioned that Roush had launched the 2018 through 2020 Mustang 2.3-liter Performance Pac Level 1 package that included a new calibration and a cold air intake. Roush has also launched the Roush Performance Pac Level 2 for the 2018 through 2020 2.3-liter Mustang. The difference between the two packs only comes in that Level 2 also includes a Roush exhaust system.
The Roush Level 2 pack fits 2.3-liter EcoBoost inline-four-cylinder engines, excluding the high output 2.3-liter EcoBoost Mustang, and Mustangs fitted with the Ford Active Exhaust. The cold air intake includes a high flow, high-capacity, washable, and reusable dry element performance air filter that the user never has to oil. Combined with the calibration that includes throttle mapping for a more spirited feel, the cold air intake adds 34 horsepower and 37 pound-feet of torque over the stock engine.
The big addition you get for the Level 2 is an included Roush axle-back exhaust kit. Roush promises that the exhaust system will give the Mustang a more aggressive tone and includes dual-wall exhaust tips and dual single-tip high-flow mufflers. It’s worth noting that the addition of the axle-back exhaust system does not gain any power over the Level 1 Performance Pac.
Cars fitted with either system will produce the same 296 horsepower and 349 pound-feet of torque. The other major difference is the price. The Roush Performance Pac Level 2 sells for $1529 compared to the $935 price of the Level 1 Pac. Buyers want to be sure they like the sound that the Roush exhaust system offers before they spend roughly $600 in additional money. If all you want is the power, stick with the Level 1 Pac.
