If you’re a Mercedes-Benz enthusiast looking to unleash the full potential of your E63 S W213, upgrading your E63 downpipe is one of the most impactful modifications you can make. Whether you own the W213 sedan, S213 wagon, C238 coupe, or A238 cabriolet, a high-quality downpipe can deliver noticeable gains in power, sound, and overall performance. In this guide, we’ll explore the benefits of downpipes, considerations when choosing one, and why it’s an essential upgrade for your E63 S.
What Is a Downpipe?
A downpipe is a critical component in your vehicle’s exhaust system that connects the turbocharger to the rest of the exhaust. For the Mercedes-AMG E63 S W213, the stock downpipe is designed to meet emissions standards and ensure quiet operation. While this is great for everyday driving, it limits the engine’s potential by restricting airflow and reducing performance.
Why Upgrade to Aftermarket Downpipes?
Aftermarket downpipes are engineered to enhance performance by increasing exhaust flow. Here’s what you can expect from a high-performance downpipe upgrade:
1. Increased Horsepower and Torque
Replacing the restrictive factory downpipe with a larger, freer-flowing aftermarket option allows your turbocharged 4.0L V8 engine to breathe better. This results in more horsepower and torque across the RPM range, making your E63 S even more thrilling to drive.
2. Improved Throttle Response
Enhanced exhaust flow reduces turbo lag, delivering quicker throttle response and a more immediate power delivery.
3. Enhanced Exhaust Note
An aftermarket downpipe unleashes the true sound of your AMG engine. You’ll enjoy a deeper, more aggressive exhaust note that matches the car’s performance pedigree.
4. Support for Other Modifications
If you plan to install a tune or additional performance upgrades, a high-quality downpipe is a foundational modification that optimizes the benefits of these enhancements.
Choosing the Right Downpipe for Your E63 S W213
Not all downpipes are created equal. When shopping for an upgrade, consider the following factors:
Material and Build Quality
Look for downpipes made from premium materials like 304 stainless steel, which offers excellent durability, corrosion resistance, and heat tolerance.
Catless vs. Catted Downpipes
Catless Downpipes: Provide maximum performance gains and the loudest exhaust note but may not comply with emissions regulations.
Catted Downpipes: Include high-flow catalytic converters to balance performance and emissions compliance while reducing exhaust odor.
Fitment
Ensure the downpipe is specifically designed for your E63 S W213, whether you have a sedan, wagon (S213), coupe (C238), or cabriolet (A238). Proper fitment ensures easy installation and optimal performance.
Tuning Requirements
Many aftermarket downpipes require an ECU tune to maximize performance and prevent check engine lights. Check if your downpipe requires tuning and budget accordingly.
Installation and Considerations
Installing a downpipe is a moderately complex process that requires mechanical expertise. It’s recommended to have the installation performed by a professional or at a reputable performance shop. Additionally, consider these points:
Emissions Compliance: Research local regulations to ensure your chosen downpipe is street legal in your area.
Maintenance: Regularly inspect your downpipe for signs of wear or damage, especially if you opt for a catless version.
