For M113 M113k Benz SL55 CLS55 E55 C55 SL500 CLS500 E500 AMG Mid-Length Headers

The XS-POWER Mercedes-Benz M113 and M113K mid-length performance header system is designed for compatible Mercedes-Benz and AMG V8 applications requiring a higher-flow exhaust manifold and downpipe configuration.

These mid-length exhaust headers are designed to reduce exhaust restriction and improve exhaust-gas flow compared with the restrictive factory exhaust manifold configuration they replace.

The larger performance-oriented exhaust passages provide increased flow capacity for both naturally aspirated M113 V8 and supercharged M113K AMG V8 performance applications.

The header system also changes the exhaust character of the M113/M113K V8, producing a stronger and more aggressive exhaust note when combined with the vehicle's existing exhaust system.

Designed for compatible Mercedes-Benz vehicles equipped with the M113 naturally aspirated V8 and M113K supercharged AMG V8 engine platforms.

The supplied application information identifies compatibility with both left-hand-drive (LHD) and right-hand-drive (RHD) vehicles. Exact engine, chassis and exhaust configuration should be verified before ordering.

This system uses a mid-length header configuration designed specifically for performance-oriented M113 and M113K exhaust applications.

Replacing the restrictive factory exhaust manifold section with a higher-flow header design can reduce restriction as exhaust gases leave the cylinder heads.

Improved exhaust flow is especially relevant on modified M113 and M113K engines where increased engine airflow creates additional demand on the exhaust system.

The M113K is the supercharged version of the Mercedes-Benz M113 V8 platform used in several high-performance AMG applications.

A higher-flow exhaust header system can be particularly useful as part of a modified supercharged engine combination where additional airflow, boost and engine output increase exhaust-gas volume.

Compatible applications include the supplied E55 AMG, CLS55 AMG and SL55 AMG fitment information. Verify the exact vehicle configuration before installation.

The original product specification identifies typical gains of approximately 7-10% for naturally aspirated V8 applications and gains of up to approximately 15% for supercharged applications.

Performance headers can significantly change the exhaust character of the Mercedes-Benz M113 and M113K V8 by reducing restriction between the cylinder heads and downstream exhaust system.

Final exhaust volume and tone depend on the complete exhaust configuration, including catalytic converters, resonators, center section and rear mufflers.

The header kit includes the corresponding downpipes.

The supplied downpipes are designed to form the transition between the performance headers and the remaining exhaust system. See the listing photographs for the components supplied.

Professional exhaust installation and fabrication are strongly recommended.

Existing exhaust modifications, aftermarket exhaust systems, vehicle configuration and previous repairs can affect installation. The installer should inspect and test-fit the complete system before final welding.

• Professional installation is strongly recommended.
• Exhaust welding and fabrication are required.
• Test-fit headers and downpipes before final welding.
• Confirm M113 / M113K engine and vehicle configuration before ordering.
• Verify clearance around steering, transmission, chassis and surrounding components.
• Modified vehicles may require additional fabrication.
• Inspect all exhaust connections after installation and initial heat cycles.
• Installation labor, fabrication and vehicle-specific adjustments are not included.

• Mercedes M113 / M113K Mid-Length Performance Headers
• Matching Downpipes

Please compare the listing photographs with your vehicle and confirm the components included before beginning installation.

What engines are these headers designed for?

Will these fit an E55 AMG?
Compatible E55 AMG M113/M113K applications are included in the supplied fitment information. Confirm the exact engine and chassis configuration before ordering.

Will these fit an SL55 AMG?
The supplied fitment information includes compatible Mercedes-Benz SL55 AMG M113K applications.

Will these fit a CLS55 AMG?
The supplied fitment information includes compatible CLS55 AMG M113K applications.

Will these fit a C55 AMG?
The supplied fitment information includes compatible C55 AMG M113 applications.

Do these fit left-hand-drive and right-hand-drive vehicles?
Yes. The supplied product information identifies compatible LHD and RHD applications.

Are downpipes included?
Yes. The header kit includes downpipes.

Do the downpipes bolt directly to the existing exhaust?
No. The supplied downpipes must be welded to the existing exhaust system.

Are these shorty or long-tube headers?
These are a mid-length performance header design.

Will these make more horsepower?
The higher-flow header design reduces exhaust restriction and can support increased engine output. Actual horsepower and torque changes depend on the complete vehicle configuration and are not guaranteed.
