Introduction to the Meisterschaft Exhaust for the W205 C63

The Mercedes-AMG W205 C63 is already a formidable machine, but many owners seek a more aggressive exhaust note and marginal performance gains. The Meisterschaft Exhaust System is a top-tier aftermarket choice, known for its high-quality construction and distinctive sound. This guide provides a detailed, step-by-step installation process, covering everything from preparation to final checks. By following these instructions carefully, you can complete the swap in a garage or driveway with basic tools. The result is a deeper, more pronounced exhaust tone that truly brings the M177 engine to life.

Why Upgrade to a Meisterschaft Exhaust?

Before diving into the install, it helps to understand the benefits. The stock exhaust is designed for a balance of sound, emissions, and cost. The Meisterschaft system is typically constructed from T304 stainless steel or titanium, with mandrel-bent tubing for optimal flow. This reduces backpressure slightly, which can improve throttle response and add a few horsepower when paired with a tune. The primary upgrade is the sound: a richer, more aggressive growl at idle and a wail at high RPMs. Many systems also feature valve control (GT or GTS variants) that allow you to switch between quiet and loud modes.

For W205 C63 owners, popular configurations include the Meisterschaft GT (single-wall or double-wall tips) or the GTS (multi-chamber design). Always confirm compatibility with your specific model year (2015-2018 for sedan/coupe, 2018-2023 for facelift). Visit the official Meisterschaft website for current product listings and sound clips.

Tools and Materials Required

To ensure a smooth installation, gather all items before lifting the car. Using correct tools reduces frustration and prevents damage.

Required Tools

  • Socket set (metric, 10mm to 18mm sockets)
  • Ratchet wrench set (for tight spaces)
  • Torque wrench (range 20-100 Nm)
  • Long extension bars (for reaching exhaust bolts)
  • Hydraulic jack and two sturdy jack stands
  • Safety goggles and mechanic gloves
  • Penetrating oil (e.g., WD-40 or Liquid Wrench)
  • Cutting tool (reciprocating saw or angle grinder) – only if removing OEM exhaust tips or if bolts are seized
  • Flathead screwdriver or pry bar (for rubber hangers)
  • Rags and a drain pan for any fluid drips

Supplied Hardware

  • Meisterschaft exhaust system (center section, rear section, tips, hardware)
  • New gaskets (if not pre-installed)
  • Mounting bolts, nuts, washers

We recommend using a reputable supplier like ECS Tuning for additional exhaust gaskets or replacement hardware.

Safety and Preparation

Work in a well-ventilated area – preferably a garage with the door open or outside. The vehicle must be on a level surface. Never rely solely on a jack; use jack stands rated for at least 3 tons. Chock the rear wheels. Allow the car to cool down completely before working near the exhaust system to avoid burns. Wear eye protection and gloves throughout.

Lifting the Vehicle

Locate the factory jack points under the side skirts. Place the jack under the designated front or rear lift point, and raise the car high enough to slide jack stands under the frame rails. Set the stands at the proper height and double-check stability. For exhaust removal, you'll want enough clearance to work comfortably – typically 18-24 inches of lift.

Removing the Stock Exhaust System

Removing the factory exhaust is the most labor-intensive part. Proceed methodically to avoid damaging the system or the vehicle.

Step 1: Disconnect Sensors and Valves (If Applicable)

On the W205 C63, the stock exhaust has two electronic valves (one per side) that control sound. Unplug the valve actuators by pressing the clip and pulling gently. There are also oxygen sensors in the downpipes – you may need to unclip the O2 sensor harness if your Meisterschaft requires relocating them (though most cat-back systems don't interfere). Use a coolant hose or zip tie to secure sensors out of the way.

Step 2: Loosen Exhaust Hangers and Bolts

Starting at the rear, spray penetrating oil on the four rubber hanger brackets and the bolts connecting the center pipe to the downpipes (two bolts per side, usually 13mm or 15mm). Let the oil sit for 5-10 minutes. Remove the bolts holding the exhaust to the downpipes using a socket and ratchet. If they are stubborn, apply heat with a propane torch (carefully, away from fuel lines).

Step 3: Support and Lower the Exhaust

Place a jack with a block of wood under the rear section of the exhaust to support its weight. Then, remove the hanger hooks using a flathead screwdriver to pry the rubber isolators loose. With all hangers free and bolts removed, you can lower the stock exhaust as one piece (it's long and heavy – have a helper support the front and rear). Slide the exhaust out from under the car. On some models, you may need to remove the rear bumper or diffuser trim to slide the tips out – check clearance before pulling.

Step 4: Transfer Hardware

If your Meisterschaft system uses the factory hanger locations, you do not need to remove the rubber isolators from the chassis. But if your kit includes new hangers, leave them attached to the car for now.

Installing the Meisterschaft Exhaust System

With the old system out, you can install the new Meisterschaft. Follow the manufacturer's instructions for orientation and torque specs – these may vary by generation.

Step 1: Pre-Assemble Sections

Most Meisterschaft systems arrive in two or three sections: a center section with a resonator or x-pipe, a rear muffler section, and individual tip assemblies. Lay them on the floor and loosely attach the flanges using the supplied bolts. Do not tighten yet – alignment is easier when everything is loose.

Step 2: Position and Attach to Downpipes

Slide the assembled system under the car. Connect the front flange of the center section to the downpipe exhaust connections. Use new gaskets if provided (or reuse OEM if in good condition). Insert bolts and hand-tighten. Ensure the gasket is seated properly to prevent leaks.

Step 3: Install Hangers and Align

Lift the exhaust into position and slide the rubber hanger isolators onto the Meisterschaft's hanger hooks. You may need to use a pry bar or lubricant (soap and water) to get them on. Adjust the position of the exhaust so that the tips are centered in the bumper cutouts and the system does not contact the underbody or heat shields. Leave all bolts and clamps finger-tight.

Step 4: Connect Tips

If your exhaust uses slip-on tips, slide them onto the rear outlets and adjust depth and angle. Many Meisterschaft tips are secured by set screws or a clamp. Tighten them evenly so they are square with the bumper. Some owners prefer to leave the tips slightly recessed (5-10mm) for a factory look.

Step 5: Reconnect Valve Actuators (If Retained)

If you opted for a Meisterschaft system with electronic valve control (some GT versions), plug the actuators back in. For non-valved systems, simply leave the OEM valve motors disconnected and tie them up out of the way – you may get a CEL if the car expects them. To avoid that, many owners install a resistor plug or have a tune that deletes the valve diagnostics. Check MBWorld forums for specific W205 C63 valve bypass solutions.

Final Adjustments and Torqueing

Once everything is loosely assembled, you can finalize position and tighten all fasteners.

  • Check that the exhaust is hanging evenly with no side-to-side lean. Measure the gap between each tip and the bumper trim.
  • Using a torque wrench, tighten the downpipe-to-exhaust bolts to 35-40 Nm (26-30 ft-lbs) (or as specified by Meisterschaft). Over-tightening can strip threads or warp flanges.
  • Tighten the flange bolts connecting the center and rear sections to similar torque.
  • Ensure all clamps are snug but avoid over-tightening clamp straps – they can crack the pipe.
  • Reattach any heat shields that were removed (often the stock ones can be reinstalled).

After torqueing, start the engine and listen for leaks at each joint. A small exhaust leak will cause a ticking sound and may trigger an O2 sensor code. If you hear a leak, shut off the engine, allow it to cool, and retighten the suspect flange. It's normal to smell some burning off of oils from the new metal for the first few heat cycles.

Post-Installation Checks and Break-In

After the initial start-up, take the car for a short test drive. Let the exhaust heat cycle a few times. Then re-inspect all bolts – they may loosen slightly as the system settles. Re-torque after the first 50-100 miles.

Common Issues

  • Drone: The Meisterschaft GT can exhibit drone at 1500-2000 RPM under light throttle. This is normal for a free-flowing system. Adding a resonator or using the valve-closed setting can help.
  • Hanger Noise: If the exhaust contacts the underbody, you'll hear a metallic rattle. Adjust hanger positions or add rubber isolator spacers.
  • Check Engine Light: If you disconnected O2 sensors or removed the valve circuitry, you may need a tune or a sensor extension harness.

Many enthusiasts pair the Meisterschaft with a stage 1 tune for full benefit. Visit Weistec Engineering for tuning options that maximize the exhaust upgrade.

Performance and Sound Expectations

The Meisterschaft exhaust transforms the W205 C63 character. At idle, you get a deeper rumble with subtle pops. Under full throttle, the sound is raw and aggressive – significantly louder than the stock sport exhaust. The valved versions allow you to keep things civilized in Comfort mode. On a dyno, you may see gains of 5-10 hp at the wheels with no other modifications, but the real benefit is the weight savings (the Meisterschaft is often 20-30 lbs lighter than the factory system). Note that some race-oriented setups (like the GTS) can be very loud and may not be legal for street use in all areas.

Conclusion

Installing the Meisterschaft Exhaust System on your W205 C63 is a rewarding DIY project that dramatically improves the driving experience. By following this comprehensive guide, you can achieve a professional-level installation with attention to detail. Always reference the specific instructions that come with your exhaust kit, and don't hesitate to consult community resources for model-specific tips. Enjoy the new sound and the turned heads your C63 will attract.
