If youÕre a Mercedes enthusiast, there's a good chance youÕve either thought about or already started modifying your ride. One of the most impactful upgrades you can make to unleash your E63Õs performance is a mercedes e63 downpipe install. Not only does this upgrade enhance horsepower and torque, but it also wakes up your carÕs sound in a serious way.
LetÕs break down what a downpipe is, why it matters, and how to approach the installation processÑwhether you're doing it yourself or having a shop handle it.
What Is a Downpipe?
The downpipe is part of your vehicleÕs exhaust system. It's the section of piping that connects the turbocharger to the rest of the exhaust. In the case of the Mercedes-AMG E63, which features a biturbo V8 engine, the downpipe plays a critical role in how gases exit the engine and flow through the exhaust system.
Stock downpipes typically include restrictive catalytic converters that limit exhaust flow. An aftermarket downpipeÑoften high-flow or catlessÑremoves these restrictions, allowing for improved turbo spool times, better throttle response, and an overall boost in power.
Why Consider a Mercedes E63 Downpipe Install?
Here are a few compelling reasons why enthusiasts opt for a Mercedes E63 downpipe install:
- More Power: Upgrading to an aftermarket downpipe can add 20Ð40+ horsepower, especially when paired with a tune.
- Better Sound: The E63 already sounds aggressive, but a performance downpipe unlocks a deeper, throatier tone. YouÕll definitely turn more heads.
- Faster Turbo Spool: Reduced backpressure allows your turbos to spool more quickly, improving acceleration and responsiveness.
- Increased Efficiency: With exhaust gases exiting more freely, your engine doesnÕt have to work as hard, leading to better performance.
Just keep in mind: with great power comes great responsibility (and sometimes, louder cold starts).
DIY or Professional Installation?
A Mercedes E63 downpipe install isn't the easiest job, but it's certainly doable for the mechanically inclined. HereÕs what you need to know:
Tools Required:
- Socket set
- Torque wrench
- Jack and jack stands or a lift
- Penetrating oil (for stubborn bolts)
- Safety gloves and eye protection
Basic Installation Steps:
- Cool Down: Make sure the car is cool. The exhaust system gets extremely hot and can take hours to cool down.
- Lift the Vehicle: Securely raise the vehicle using jack stands or a lift.
- Remove Stock Downpipes: This involves unbolting the stock units from the turbo and mid-pipe sections. Be prepared for tight spaces and possibly corroded bolts.
- Install New Downpipes: Line up your aftermarket downpipes and bolt them in place. Use new gaskets and check for fitment.
- Check for Leaks: Start the car and listen for any exhaust leaks. Re-torque bolts if needed.
Pro Tip:
If you're not 100% confident in your abilities, have a professional shop perform the install. Not only will it save you time and stress, but many shops offer dyno tuning packages alongside installation for max performance.
Tuning and Emissions
ItÕs important to note that a Mercedes E63 downpipe install often requires an ECU tune to get the most out of the modification. Some aftermarket downpipes may trigger a check engine light (CEL) without a proper tune.
Also, emissions regulations vary by state and country. Some downpipes are not street-legal and are intended for off-road or track use only. Always check your local laws before making the switch.
Community Feedback
The Mercedes-AMG community is full of owners whoÕve made this upgrade and never looked back. YouÕll find countless posts and YouTube videos praising the transformation in performance and sound after a Mercedes E63 downpipe install.
Many say it's the single best bang-for-your-buck mod for the E63. Combine it with an ECU tune and performance intake, and you're looking at supercar-level performance from your luxury sedan.
Final Thoughts
Whether you're chasing faster 0Ð60 times, a more aggressive exhaust note, or simply want to experience your E63 in its full glory, a Mercedes E63 downpipe install is a worthwhile upgrade. It adds performance, character, and excitement to an already incredible machine.
Just remember to do your research, buy quality parts, and either follow a trusted install guide or seek professional help. Once it's done, the smile on your face will say it all.
