Mercedes E63 W213 Catted vs Catless Downpipes & Lamborghini Urus Downpipes Explained
mercedes e63 w213 catted and catless downpipes
If you’re a car enthusiast, especially someone who thrives on high-performance European beasts, then understanding the role of downpipes in performance tuning is a must. Two of the most popular performance vehicles that tuners love to upgrade are the Mercedes E63 W213 and the Lamborghini Urus. In both cases, aftermarket downpipes—whether catted or catless—can significantly enhance power output, exhaust sound, and turbo efficiency.
In this guide, we’ll take a deeper dive into the world of catted and catless downpipes for the Mercedes E63 W213 and the performance benefits of upgraded downpipes for the Lamborghini Urus.
What Are Downpipes and Why Do They Matter?
In turbocharged engines, the downpipe is the first section of exhaust that comes directly off the turbo. It plays a vital role in how exhaust gases exit the system, which in turn influences turbo spool time, backpressure, and overall performance. Upgrading your downpipe—especially removing factory restrictions like catalytic converters—can lead to significant horsepower gains.
Mercedes E63 W213 Downpipes: Catted vs Catless
The Mercedes-AMG E63 W213 is a 4.0L twin-turbocharged V8 monster known for its brutal acceleration and luxury interior. However, there’s always room for improvement—and that’s where aftermarket downpipes come in.
Catted Downpipes
Catted downpipes retain a high-flow catalytic converter, which helps reduce emissions and keeps your car street legal in most regions. These downpipes balance performance with legality, offering increased flow over stock components without completely removing emission control devices.
- Advantages:
- Improved throttle response
- Legal in many areas
- Minimal exhaust smell
- Slightly louder and deeper tone
- Ideal For: Daily drivers who want performance without the legal headaches.
Catless Downpipes
Catless downpipes remove the catalytic converters entirely, allowing for unrestricted exhaust flow. This maximizes turbo efficiency and leads to the most noticeable performance gains.
- Advantages:
- Maximum horsepower and torque gains
- Aggressive exhaust note
- Faster turbo spool and reduced lag
- Disadvantages:
- Not emissions-compliant in most areas
- Can trigger check engine lights
- Stronger exhaust odor
- Ideal For: Track-only setups or off-road use.
For serious tuners, a Mercedes E63 W213 catless downpipe paired with a proper ECU tune can yield up to 70+ additional horsepower, depending on supporting mods.
Lamborghini Urus Downpipes: Super SUV, Super Sound
The Lamborghini Urus is not just a luxury SUV—it’s a 641-horsepower twin-turbo V8 beast. Like the E63, the Urus can benefit tremendously from upgraded downpipes.
Aftermarket downpipes for the Urus are typically catless or sport catted versions, designed to eliminate restrictions and let the engine breathe. The results? Sharper throttle response, an aggressive exhaust tone, and improved high-RPM power.
- Catless Downpipes: Provide the loudest, rawest exhaust note. Expect major pops, crackles, and serious gains in performance. Ideal for track use or for those who don’t need to meet emissions regulations.
- Catted Downpipes: Designed for a compromise between performance and compliance. They use high-flow catalytic converters to keep emissions somewhat in check while still improving exhaust flow.
One of the main draws of lamborghini urus downpipes is the transformation in exhaust sound—turning your luxury SUV into a roaring bull.
Final Thoughts
Whether you’re upgrading your mercedes e63 w213 catted and catless downpipes or enhancing your Lamborghini Urus downpipes, the results are transformative. You’ll gain power, sound, and turbo response—elevating the entire driving experience.
Just remember: catless downpipes offer the most performance but come with legal and environmental trade-offs. Catted downpipes are a great middle-ground solution for those who want gains without going fully aggressive.
In either case, always pair your downpipe upgrade with an appropriate ECU tune to avoid check engine lights and fully unlock performance.
