Mercedes E63 W213 & Lamborghini Urus Downpipes Explained
When it comes to high-performance luxury vehicles, few names strike as much excitement as Mercedes-AMG and Lamborghini. For automotive enthusiasts looking to extract every bit of horsepower and aggression from these machines, upgrading the downpipes is often one of the first — and most impactful — modifications. Whether you’re piloting the brutal mercedes e63 w213 catted and catless downpipes or taming the beastly Lamborghini Urus downpipes, understanding how these parts work and what they offer is crucial to making the most out of your investment.
What Are Downpipes and Why Do They Matter?
Downpipes are an essential component in a turbocharged engine’s exhaust system. They channel the hot gases from the turbo to the rest of the exhaust. This path can be restrictive in stock configurations, especially due to factory-installed catalytic converters (cats) that focus on emissions rather than performance. Upgrading to aftermarket downpipes — either catted or catless — significantly improves airflow, reduces turbo lag, and often unlocks a much more aggressive exhaust note.
Mercedes E63 W213 Downpipes: Catted vs. Catless
The W213 generation of the Mercedes-AMG E63 is a twin-turbocharged V8 monster with performance baked into its DNA. However, factory downpipes can leave horsepower on the table. That’s where aftermarket options come in.
Catted Downpipes
High-flow catted downpipes replace the restrictive stock cats with performance-oriented catalytic converters. They offer improved exhaust flow while still maintaining a level of emissions compliance, which can be important in areas with strict regulations. You’ll get a noticeable bump in power and a throatier exhaust tone, all while avoiding that raw “racecar” smell that catless pipes can bring.
Catless Downpipes
For those who prioritize raw performance and don’t mind the louder volume (and potential for check engine lights), catless downpipes are the way to go. They eliminate the catalytic converter entirely, leading to better flow and faster spool-up times. However, keep in mind these are intended for off-road or track use due to emissions laws in many countries.
Swapping in Mercedes E63 W213 catted and catless downpipes doesn’t just mean more horsepower — it often results in cooler exhaust temps, improved throttle response, and that intoxicating V8 roar echoing with even more clarity.
Lamborghini Urus Downpipes: Waking the Bull
The Lamborghini Urus, a super SUV with a twin-turbocharged V8 under the hood, is already a powerhouse. But its stock exhaust is surprisingly tame for something with such wild heritage. That’s where downpipe upgrades come into play.
Installing aftermarket lamborghini urus downpipes is one of the best ways to transform the Urus into the growling, crackling monster it truly is. Much like the E63, owners can choose between catted and catless options depending on local laws and sound preferences.
Urus downpipes offer dramatic gains in sound, especially under heavy acceleration or downshifting. Turbo lag is also reduced, giving you sharper throttle response and an even more engaging driving experience. When paired with a tune, these upgrades can easily add 50–100 horsepower, turning the already potent Urus into a true track-ready beast — all while hauling groceries if needed.
Tuning & Considerations
Both the E63 and Urus will benefit significantly from ECU tuning after installing downpipes. A tune helps optimize air-fuel ratios, prevent warning lights, and maximize performance gains. It’s not mandatory, but it’s highly recommended if you’re investing in this kind of upgrade.
It’s also worth noting that catless setups may fail emissions tests in many regions. If your car is a daily driver in an emissions-regulated area, high-flow catted pipes are a safer, more street-legal choice.
Final Thoughts
Upgrading downpipes on high-end performance vehicles like the Mercedes-AMG E63 and Lamborghini Urus is about more than just numbers — it’s about transforming how the car feels, sounds, and responds. Whether you’re cruising city streets or chasing apexes at the track, the right downpipes will make your machine breathe fire like it was meant to.
