Among the entire American automotive industry, one variable that can be agreed upon unanimously is the sound of a roaring V8 flying down the highway or street. The Mustang is exceptionally familiar with this characteristic; without the theatre of sound that the S550 Mustang produces, it wouldn't be the most successful modern stallion to date. In today's world of sound regulation and emissions, new enthusiasts are always wondering how they can get more volume, rumble, and performance out of their pony's exhaust.

The balance of air properly-being brought in and out is crucial to ensuring a proper air/fuel ratio to promote acceleration and power throughout your S550 Mustang engine RPM band.

S550 Mustang Powertrain

Throughout Mustang's legendary history, performance has been at the center of each stallion to roll out from Detroit. Every single pony since 1964 has strived to push the boundaries of what is possible in powertrain and engine performance. Like all Mustang generations, Ford knew that as technology advanced, so must America's original pony car powertrain. Luckily for enthusiasts new and veteran to the Mustang community, they got fortunate in 2015 when both the second generation of the legendary 5.0L Coyote engine and 2.3L EcoBoost four-cylinder engine debuted. Both engines offered the ability to market themselves to potential new enthusiasts and consumers in a way that hadn't been done beforehand.

The characteristics that make these two engines so unique are the ability to have easy access to performance modifications on-demand thanks to the automotive aftermarket. From the factory, both the Gen II/Gen III Coyote 5.0L V8 and 2.3L EcoBoost engine became so easy to modify with an abundance of performance parts that will enhance throttle response, acceleration, horsepower, and torque thanks to the help of many aftermarket companies. Now for the new S550 owners out there, you will want to plan out what goals are for your modern pony in terms of driveability, reliability, and how much power you are seeking to put down to the ground.

    S550 Mustang Steeda CAI

  • Cold Air Intake: Throughout the entire automotive aftermarket and industry, one performance modification for your vehicle and Mustang can help in power, efficiency, and airflow is to add a cold air intake. From the factory, the S550 Mustang air intake is designed to bring in a sufficient amount of air while still promoting more efficiency to meet federal regulatory standards. The more air you add to your Mustang engine, you will be promoting better performance and power throughout the RPM range.

  • S550 Mustang 2018 Intake Manifold

  • Intake Manifold: As Ford has continued to evolve the legendary Coyote engine, so has intake manifold technology to promote better CFM (Cubic Feet Per Minute) and efficiency for your Mustang's heart. It will help boost horsepower and torque at a dramatic pace to help you run with the rest of the pony's on the street or track while not breaking the bank.

  • S550 Mustang Throttle Body

  • Throttle Body: A characteristic and variable that new S550 Mustang enthusiasts need to understand are without the throttle body; you wouldn't be able to provide the air into your Mustang engine.

That is why bolting up a larger throttle body will allow for more CFM and airflow to produce more horsepower and torque.

s550 mustang suspension

S550 Mustang Suspension

When it comes to Mustang suspension, it has had its critiques over the years due to the outdated live rear axle that it came equipped with for many decades. Fortunately, the Ford and Mustang engineering team concluded that they needed to bring the S550 Mustang suspension to the twenty-first century by integrating independent rear suspension. Adding IRS (Independent Rear Suspension) engineers could give the S550 pony more balance, better handling characteristics, and revolutionizing the ride quality. Unlike the live axle found in the S197 Mustang, engineers implemented variables that would take the legendary American pony car to the next level on the race track or street.

During its debut in 2015, aftermarket companies like Steeda knew that to make it the best-handling Mustang ever, they had to find out the characteristics in which it had flaws that Ford did not implement to address from the factory. When it comes to new and experienced enthusiasts geared towards the S550 Mustang, it is essential to know your suspension goals and what application you intend to use. Some people are looking for better ride quality, stance, and handling when it comes to upgrading your 2015-2021 Mustang suspension.

    S550 Mustang Shocks & Struts

  • Shocks & Struts: From the factory, the S550 Mustang is hands down the best riding pony to be assembled from Ford. With the integration of the IRS (Independent Rear Suspension), better bushings, more sophisticated suspension geometry, and dampening, enthusiasts can enjoy a much more excellent ride while not having to worry about the rear-end staying planted at full throttle. To better ride quality, enthusiasts will need to look to even better shocks & struts for better ride quality and handling. Why should you upgrade your factory OEM shocks & struts? The reason for this is because, unlike the factory equipment, aftermarket shocks will allow you to adjust the rebound and dampening. In contrast, the factory components won't allow you to change your dampening because it is continuous valving when the suspension is in motion.

  • S550 Mustang Lowering Springs

  • Lowering Springs: The significant characteristic about lowering springs is they check off so many variables with a straightforward modification. Unfortunately, the ride height has always plagued the Mustang from the factory. Thanks to companies like Steeda, you can solve this problem from a stance standpoint by adding either linear, progressive, or dual-rate lowering springs which add the benefits of increasing handling response & ride quality, while reducing body roll!
