Upgrading your BMW’s sound and performance starts with one of the most transformative modifications you can make — the G80 Valved exhaust system. Known for its unmatched control, tone, and power gains, this system enhances every aspect of your driving experience. At Rvng RaceWorks, we believe the installation process should be just as seamless as the results. That’s why we’ve created this complete guide to help you understand how to install your G80 Valved Exhaust System correctly and efficiently, whether you’re a DIY enthusiast or relying on professional installation.
Before You Begin: Preparation is Key
Installing a G80 Valved Exhaust System isn’t overly complicated, but preparation ensures a clean, safe, and efficient process.
Tools You’ll Need
Before starting, make sure you have the following tools and materials:
- Car lift or jack stands
- Socket and wrench set
- Torque wrench
- Exhaust hanger pliers
- Penetrating lubricant (for old bolts)
- Safety gloves and goggles
Having the right tools ready before you begin ensures the G80 Valved Exhaust System installation runs smoothly without unnecessary delays.
Safety First
Always allow your exhaust system to cool before working on it. The G80’s factory exhaust can retain heat long after driving, so make sure it’s cool to the touch before removal. Secure the car properly on jack stands or a lift to prevent movement during installation.
Step 1: Removing the Stock Exhaust System
The first step in installing your G80 Valved Exhaust System is removing the OEM setup.
Disconnecting the Valves and Sensors
Locate and disconnect the stock exhaust valve actuators and any sensors attached to the mid-pipe or muffler. These components will either be reused or replaced depending on your new G80 Valved Exhaust System.
Unbolting the Factory Exhaust
Using your socket set, unbolt the factory exhaust from the downpipes and midsection. Apply penetrating lubricant to loosen any stubborn bolts. Carefully remove the hangers using pliers, supporting the system as you lower it to avoid damage.
Once the old exhaust is removed, inspect the mounting points and rubber hangers for wear. Replace them if necessary to ensure a stable fit for your new G80 Valved Exhaust System.
Step 2: Preparing the New G80 Valved Exhaust System
With the stock setup removed, it’s time to prepare your new G80 Valved Exhaust System for installation.
Inspect All Components
Before fitting, check that all components — mid-pipes, mufflers, valves, and tips — are included and undamaged. Rvng RaceWorks systems are carefully packaged, but it’s always wise to double-check.
Pre-Assemble the System
Lay out the components in their installation order. Lightly pre-fit the sections on the ground to ensure alignment and familiarize yourself with the orientation. This step will make final installation much smoother.
Step 3: Installing the New G80 Valved Exhaust System
Now comes the exciting part — fitting your new exhaust.
Mount the Midsection
Start with the mid-pipe. Align it with the downpipes and loosely connect it using the supplied hardware. Don’t fully tighten the bolts yet; keeping them slightly loose allows for adjustments later.
Attach the Rear Section and Valves
Next, install the muffler section and attach it to the mid-pipe. Ensure that the electronic valves and actuators are correctly connected to your new G80 Valved Exhaust System. If your kit uses OEM actuators, reuse the original connectors for a plug-and-play setup.
Align and Secure the Exhaust Tips
Once the rear section is in place, adjust the exhaust tips for perfect alignment with the bumper. Every G80 Valved Exhaust System from Rvng RaceWorks is designed for precise fitment, so achieving symmetry should be straightforward.
After everything looks perfect, tighten all bolts using a torque wrench according to the manufacturer’s specifications.
Step 4: Valve Connection and Calibration
The defining feature of the G80 Valved Exhaust System is its electronically controlled valves. Proper connection ensures you can switch seamlessly between quiet and aggressive modes.
OEM Integration
If your G80 Valved Exhaust System integrates with factory drive modes, connect the valve harnesses to the existing actuators. This allows the valves to respond automatically when switching between Comfort, Sport, and Sport Plus.
Remote or App-Based Controls
For systems equipped with an independent controller, follow the supplied wiring diagram to connect the power and receiver module. These systems often include wireless remotes or Bluetooth apps for valve control, giving you instant sound adjustment.
Once connected, test the valves to confirm they open and close smoothly.
Step 5: Final Checks and Testing
Before you lower the car and hit the road, it’s important to double-check your installation.
Inspect for Leaks and Clearance
Start the car and let it idle while inspecting the joints for exhaust leaks. Listen for any unusual rattles or vibrations that might indicate misalignment. Also, ensure there’s proper clearance between the exhaust and underbody components.
Valve Function Test
Cycle through your valve modes to verify that your G80 Valved Exhaust System operates as intended. When closed, the exhaust should sound subtle and refined; when open, it should unleash the deep, powerful tone the G80 is famous for.
Maintenance Tips for Longevity
To keep your G80 Valved Exhaust System performing at its best, regular maintenance is essential.
- Check Connections: Inspect clamps, bolts, and hangers periodically to ensure nothing has loosened.
- Clean Exhaust Tips: Use metal polish to maintain shine and prevent carbon buildup.
- Monitor Valves: If your system includes electronic valves, test them regularly for smooth operation.
Routine care will ensure your exhaust looks, sounds, and performs flawlessly for years to come.
