When it comes to upgrading high-performance vehicles like the Mercedes E63 W213 and Lamborghini Urus, downpipes are one of the most impactful modifications you can make. These components not only enhance exhaust flow but also play a critical role in improving horsepower, torque, and turbo spool times. Whether you’re aiming for a throatier exhaust note or shaving tenths off your track time, understanding your downpipe options—especially catted vs catless—is essential.
Mercedes E63 W213 Downpipes: Catted vs Catless Options
The Mercedes E63 W213 is a beast on its own, powered by a 4.0L twin-turbo V8. But with a performance downpipe upgrade, you can take that power even further. Downpipes replace the restrictive factory catalytic converters, allowing for greater exhaust gas flow and a quicker turbo response.
Catted Downpipes: Balance and Compliance
Catted downpipes feature high-flow catalytic converters, which strike a balance between performance and emissions compliance. They’re ideal for drivers who use their E63 W213 on the road regularly but still want a noticeable power boost and sportier sound. A catted system will:
- Reduce turbo lag
- Increase horsepower by 15–25 hp (depending on tune)
- Keep the check engine light at bay
- Maintain emissions legality in many regions
These downpipes often use a 200-cell or 300-cell catalytic converter to maintain some filtration while minimizing restriction.
Catless Downpipes: Maximum Flow, Maximum Gains
If you’re chasing peak performance and plan to hit the track or only use your car off-road, catless downpipes are your answer. These remove the catalytic converter entirely, resulting in:
- Maximum exhaust flow
- Sharper turbo spool and boost response
- Power gains up to 30+ hp with tuning
- Aggressive, raw exhaust sound
However, catless setups may cause CEL (Check Engine Light) without a tune and are not road-legal in many regions. They’re louder and more visceral, making them popular among purists and racers. mercedes e63 w213 catted and catless downpipes are both available from reputable aftermarket brands, so your choice depends on how and where you drive.
Lamborghini Urus Downpipes: Elevating an Exotic SUV
The Lamborghini Urus might be an SUV, but it packs a supercar’s heart—another 4.0L twin-turbo V8 tuned by Lamborghini to produce jaw-dropping power. As with the E63, one of the most effective upgrades is replacing the restrictive factory downpipes with performance versions.
Performance Gains with Aftermarket Downpipes
Whether you go with catted or catless downpipes for the Urus, you’re in for a transformation. Benefits include:
- 20–40 hp gains with proper ECU tuning
- Deeper, more exotic exhaust note
- Improved throttle response
- Reduced backpressure on the turbos
Unlike the E63, many Lamborghini Urus owners lean toward full-system upgrades, combining downpipes with cat-back or valved exhaust systems. Some downpipes even feature thermal coatings to reduce underhood temperatures—a crucial feature in high-performance applications.
Sound and Style Matter
The Urus isn’t just about speed; it’s also about presence. Downpipes dramatically increase the volume and tone of the exhaust, giving it that unmistakable Lamborghini roar. For owners looking to make a visual statement as well, some brands offer gold- or ceramic-coated options to match high-end engine bay aesthetics.
lamborghini urus downpipes are engineered to match the precision and aggression of the vehicle, and choosing the right brand with quality welds, material (304 stainless steel or Inconel), and compatibility with factory sensors is key.
Choosing the Right Downpipe for Your Lifestyle
When deciding between catted and catless downpipes—or choosing between brands for your Urus or W213—it’s essential to ask yourself:
- Will the car be street-driven or track-only?
- Are you looking for compliance with emissions laws?
- Is the sound level a factor for you?
- Are you planning ECU tuning?
Pairing your downpipes with proper ECU calibration is critical to avoid issues like CELs or running rich. Also, always ensure fitment with your specific vehicle model and year.
Final Thoughts
Performance downpipes for the Mercedes E63 W213 and Lamborghini Urus unlock new levels of power, sound, and excitement. Whether you prefer the refined gains of catted systems or the unfiltered rush of catless setups, the results are always thrilling. Elevate your driving experience today—because machines like these deserve to breathe freely.
