The Mercedes S-Class has long been the pinnacle of luxury and refinement. But for enthusiasts, especially those behind the wheel of an S63 AMG, luxury alone sometimes isn’t enough.
Beneath that elegant shell lies some serious performance potential, and with the right mods, you can unleash the beast while keeping that executive-class sophistication.
Whether you’re driving a W222/C217 model (2013-2020) or the newer W223 generation (2021+), there’s plenty of opportunity to enhance both performance and style in the Mercedes S-Class.
Let’s dive into the best aftermarket parts that can transform your S-Class into even more of a head-turner.
Exterior Styling Mods for the S-Class / S63 AMG
Even though the S-Class is already one of the most refined vehicles on the road, there’s always room for some more personalization. And with a few small tweaks, you can make a big difference in giving your car a more dynamic, AMG-inspired presence.
Maybach-Style Front Grille (W223)
For the 2021+ W223 generation, the Maybach-style front grille adds some instant appeal to your front end. With its vertical chrome slats and commanding design, it transforms the front end of your S-Class from subtle to statement.
It’s a direct-fit replacement to the stock grill, meaning no cutting, drilling, or complicated installation is needed, and it pairs perfectly with darker exterior trims or carbon fiber accents.
Carbon Fiber Mirror Caps (W222 / W223)
A subtle yet premium touch that instantly elevates the look of your car. The carbon fiber mirror caps for the S-Class and S63 AMG are made to OEM specification, using the same factory mounting points for a perfect fit.
Not only do they tie together other carbon fiber elements, but they’re also super durable and resistant to fading over time.
Performance Mods for the Mercedes S-Class / S63 AMG
Stock S-Class’s aren’t short on power, especially in AMG form. But if you’ve ever wanted it to sound a little deeper, or have a bit more throttle, these performance mods could be what you’re looking for.
Performance modifications for the Mercedes S63 AMG is where the biggest transformation happens.
They’ll help you unlock a deeper tone, sharper response, and a much more engaging driving experience.
Valved Sport Exhaust Systems (W222 / W223)
A valved exhaust system is one of the best mods you can add to your S-Class or S63 AMG as it can completely change the character of your car.
These systems allow you to switch between a refined, quiet mode for cruising and an aggressive, open-valve sound when you want to hear that V8 (or V12) roar, all with the flick of a switch.
These systems not only improve sound but also help reduce backpressure, increasing throttle response and efficiency. For many owners, this is the must-have first mod if you’re looking to up the performance of your Mercedes S-Class.
GCA has a range of different exhaust systems to fit the variety of S-Class models, including the S580, S63 AMG, the S500/550, S560, and S-Class. No matter your model, we’ve got you covered.
Downpipes & Race Pipes
If you’re serious about performance, downpipes are where you’ll really start to see results.
The S63 AMG in particular benefits massively from high-flow downpipes which help improve turbo spool, reduce backpressure, and unlock a deeper, throatier sound the stock system can’t deliver.
Each set is designed with integrated heat shielding and comes in both racing (catless) high-flow cat configurations, depending on your build goals and local emissions rules.
Always check your local rules & regulations regarding emissions and whether a downpipe or race pipe is allowed in your area.
Cold Air Intakes (W222/C217)
To complement your exhaust and downpipes, upgrading your intake system is another smart move.
A Carbon Fiber High-Flow Cold Air Intake for the S500, S550, and S63 AMG will help your engine breathe better by drawing in cooler, denser air for a more efficient combustion.
You’ll feel the difference in throttle response immediately, and it gives a satisfying induction sound under acceleration. Plus, the carbon fiber housing looks incredible under the hood.
Combining Mods for the Ultimate S-Class Experience
While each of these upgrades makes a noticeable difference on its own, the real transformation happens when you start to combine them, and with a car a luxurious as the Mercedes S-Class or S63, it’s a no brainer:
-
Valved exhaust + downpipes → unmatched sound and performance
-
Cold air intake + downpipes → improved airflow and turbo efficienc
- Mirror caps + Maybach-style grille → elegant yet sporty exterior refresh
Together, these mods turn your already luxurious S-Class into a refined performance machine that looks and sounds the part.
Which Mod Should You Get First?
That ultimately depends on what you’re chasing:
-
For visual upgrades: Start with Maybach-style grille. It’s affordable, easy to install, and will completely change the look of your car.
-
For sound and driving feel: The valved exhaust system is the top choice, it wakes the car up and gives you full control over your sound profile.
- For serious performance: Combine a valved exhaust with high-flow downpipes and a carbon intake to bring out the best from your engine.
The Mercedes S-Class and S63 AMG are more than just luxury sedans - they’re high-performance machines waiting to be unleashed.
With a few carefully chosen aftermarket parts, you can enhance not only how your car looks, but how it feels, sounds, and performs every time you start it up.
