Power and Precision: Upgrading Mercedes E63 W213 and Lamborghini Urus Downpipes the Right Way
work withmarket
If you’ve ever driven a true performance machine, you know the feeling — that deep surge of torque, the aggressive exhaust note, the instant throttle response. Cars like the Mercedes E63 W213 and the Lamborghini Urus are built to deliver exactly that. But for enthusiasts who always want more, upgrading the downpipes is often the first serious modification.
When we talk about mercedes e63 w213 catted and catless downpipes, we’re stepping into the world of real performance engineering — not just cosmetic tuning.
Why Downpipes Matter
A downpipe connects the turbocharger to the rest of the exhaust system. In factory form, most downpipes are restrictive because they prioritize emissions compliance and noise control. That’s understandable. But restriction also limits performance.
Upgrading to high-flow catted or catless downpipes reduces backpressure. This allows exhaust gases to exit more efficiently, helping the turbo spool faster. The result? More horsepower, stronger torque, and sharper throttle response.
For vehicles like the E63 W213 with its handcrafted AMG V8, or the twin-turbocharged Lamborghini Urus, the gains can be dramatic.
Mercedes E63 W213 Catted vs. Catless Downpipes
The W213-generation E63 AMG is already a monster from the factory. With a 4.0L twin-turbo V8, it produces serious power. But enthusiasts often look to unlock even more potential.
Catted Downpipes
High-flow catted downpipes include performance catalytic converters. They improve exhaust flow while still maintaining some emissions control. Benefits include:
- Noticeable horsepower and torque gains
- Reduced turbo lag
- Deeper, sportier exhaust tone
- Lower chance of strong exhaust smell
- Better compatibility with daily driving
Catted options are ideal for drivers who want performance without going fully race-spec.
Catless Downpipes
Catless downpipes remove the catalytic converters entirely. This creates maximum exhaust flow and unlocks the highest performance potential.
Benefits include:
- Maximum power gains
- Aggressive, raw exhaust sound
- Faster turbo spool
- Ideal for tuned or stage 2 setups
However, catless systems may trigger check engine lights without proper tuning and are typically recommended for off-road or track use.
Choosing between them depends on how you use your E63 — daily luxury performance or full aggressive build.
Lamborghini Urus Downpipes: Super SUV, Super Sound
The Lamborghini Urus is not your typical SUV. It shares its DNA with high-performance engineering and produces breathtaking acceleration for a vehicle of its size. But factory exhaust systems are still somewhat restrictive.
Upgrading lamborghini urus downpipes transforms the Urus into something even more dramatic.
With performance downpipes installed, owners often report:
- Sharper throttle response
- Increased horsepower and torque
- Louder, more exotic exhaust tone
- Enhanced turbo efficiency
- Better results when combined with ECU tuning
The Urus already sounds aggressive, but aftermarket downpipes bring out the raw Lamborghini character — deeper, louder, and more emotional.
Performance Gains: What to Expect
When paired with proper ECU tuning:
- Gains of 60–120+ horsepower are possible depending on setup
- Significant torque increases across the RPM range
- Improved mid-range pull
- Faster acceleration
Stage 2 tuning combined with high-quality downpipes can dramatically transform both vehicles. It’s not just about peak power numbers — it’s about how the car feels when you press the throttle.
Installation and Tuning Considerations
Professional installation is strongly recommended. These vehicles feature tight engine bays and complex turbo systems. Poor installation can lead to exhaust leaks or fitment issues.
