W463 G-CLASS CAT-BACK EXHAUST
This exhaust system is designed for the Mercedes-Benz G-Class W463 platform and is intended for selected G55, G63 and G500/G550 models.
Cat-back systems replace the exhaust components located downstream of the catalytic converters. Depending on the system, this can include the rear piping, mufflers and exhaust tips.
COMPATIBLE APPLICATIONS
The supplied application range covers:
- Mercedes-Benz G55 AMG: 2004–2012
- Mercedes-Benz G63 AMG: 2012–2017
- Mercedes-Benz G500/G550: 2004–2017
Some aftermarket systems specify narrower application ranges, such as G55 2008–2012, G63 2012–2017 and G500/G550 2013–2017. Earlier G-Class models may require modification during installation.
G55 AMG
The G55 AMG uses a 5.5L supercharged V8 in the relevant W463 applications.
The cat-back system can be configured around the G55’s exhaust routing and side-exit configuration, depending on the specific system.
Verify the model year and existing exhaust configuration before ordering.
G63 AMG
Selected W463 G63 AMG models from 2012–2017 use the 5.5L twin-turbocharged V8.
Aftermarket W463 G63 cat-back systems are available in stainless-steel configurations with different muffler and valve arrangements.
G500 / G550
The G500/G550 application covers multiple engine configurations across the W463 production period.
Some systems specifically list:
- G550 5.5L
- G550 4.0L
- Selected 2009–2017 W463 applications
Because the engine and exhaust configuration changed during the W463 production period, verify the exact engine and chassis specification before purchase.
EXHAUST COMPONENTS
Depending on the supplied configuration, the system may include:
- Left-side exhaust pipe
- Right-side exhaust pipe
- Center pipes
- Rear mufflers
- Resonators
- Exhaust valves
- Valve-control module
- Remote control
- Exhaust tips
- Mounting brackets
- Clamps
- Flanges
- Installation hardware
Only components specifically shown or stated in the listing should be considered included.
STAINLESS STEEL CONSTRUCTION
Many W463 cat-back systems are manufactured from stainless steel.
Available aftermarket systems include 304 stainless-steel construction, with stainless flanges, brackets and mufflers depending on manufacturer.
Benefits of stainless-steel construction include:
- Corrosion resistance
- Durable exhaust tubing
- Heat resistance
- Long service life
- Reduced surface deterioration
- Suitable material for performance exhaust applications
VALVED EXHAUST
If this listing includes exhaust valves, the valve system can control the exhaust flow through the muffler configuration.
Depending on the system, components can include:
- Exhaust valves
- Valve actuators
- Valve-control box
- Remote control
- Wiring
- Mounting hardware
Some W463 valved systems are designed to provide a quieter exhaust configuration when the valves are closed and a more open exhaust path when the valves are activated.
EXHAUST TIPS
The exhaust tips may vary according to the selected configuration.
Possible options include:
- Dual exhaust tips
- Triple exhaust tips
- Carbon-fiber tips
- Stainless-steel tips
- Black-finished tips
Confirm the exact tip design before purchase.
FITMENT & INSTALLATION
Installation requirements depend on the vehicle year and exhaust system.
Some W463 systems are designed as direct bolt-on systems, while other configurations may require modification. Certain earlier applications can require the OEM mufflers to be cut and the replacement mufflers welded into position.
Before installation:
- Confirm the exact W463 model.
- Confirm the engine.
- Confirm the model year.
- Compare the exhaust routing with the vehicle.
- Check all flange locations.
- Check exhaust hanger positions.
- Confirm tip location.
- Verify valve-control compatibility where applicable.
- Install the exhaust components.
- Check exhaust clearance.
- Check for leaks.
- Verify exhaust valve operation.
- Check bumper and body clearance.
- Confirm there is no exhaust contact or excessive vibration.

- Flanges
- Welds
- Exhaust valves
- Valve actuators
- Exhaust tips
