Exhaust Mercedes CLA-Class C117 (2013-2019)

The OEM exhaust systems for the Mercedes CLA Coupé (C117) and Shooting Brake (X117) are crafted for precise compatibility and quality. Typical designs include rectangular stainless steel outlets and dual flow for sport trims like AMG Line or Urban.

For example, the rear exhaust system with a valve for the CLA 220 Coupé W117 weighs 13.749 kg and measures approximately 2.1 m long when packed. It enhances performance and style while replacing the original part and requires a chassis VIN check for fitment.

Sport models often feature a silver rear diffuser, sport lowered suspension, diamond grille, and AMG 18-inch wheels. AMG trims (e.g., CLA 45) typically include chrome exhaust tips, red calipers, AMG Performance exhaust, and 19-inch black wheels.

A wide range of stainless steel sport exhaust systems are available aftermarket for the Mercedes CLA C117 to boost sound and performance, often as cat-back systems that fit after the catalytic converter to comply with Euro 6 emissions standards.

• Supersprint Pack AMG Cat-Back: Stainless steel complete line with link pipes and resonator delete (for CLA 200/250 models from 2015 onwards).
• Inoxcar Sport Silencer: Rear silencer maintaining original tip design, for the CLA 45 AMG 2.0 360 hp (from 2013+).
• Fox Duplex Exhausts: Duplex stainless rear silencer 2x80 mm, suitable for all CLA C117/X117 versions.
• MN-Automo Diffuser + Tips: Black ABS diffuser with chrome tips for CLA W117 (2013-2018).

Typical original outlet diameters range between 65-70 mm according to user forums, ensuring an authentic fit.

The exhaust systems for the CLA C117 are designed specifically for Euro 6 compliant engines:

• Petrol engines: M270 1.6L turbocharged engine powering CLA 180 and CLA 200 models (122-156 hp).
• High-performance AMG petrol: M133 2.0L turbo engine delivering 360-381 hp in CLA 45 AMG 4MATIC, achieving 0-100 km/h in 4.2–4.8 seconds.
• Diesel engines: OM651 2.1L turbo diesel in the CLA 220 CDI (170-177 hp).

These engines benefit from exhaust designs that balance airflow, noise reduction, and emissions compliance.

The CLA C117 features exhaust valves with valvetronic control technology in some sport and AMG models, allowing variation in exhaust flow and sound depending on driving conditions.

• Valvetronic systems use electronically controlled valves to modulate exhaust flow.
• This provides quieter operation during urban driving and a more aggressive note at higher revs or in sport modes.
• These valves can be remotely controlled or automated by the car's system to open or close depending on RPM and driver demand.

This technology enhances driving enjoyment without compromising noise regulations or comfort when desired.

When selecting an exhaust system or kit for your CLA C117, consider the following key points:

• Ensure compatibility by verifying your vehicle’s chassis number (VIN) and engine model.
• Look for stainless steel construction to resist corrosion and maintain performance longevity.
• Check if the system includes components like rear mufflers, downpipes, and exhaust tips suitable for your trim (standard or AMG).
• Consider professional installation to maintain warranty and ensure correct fitment, especially for valvetronic or sport exhaust systems.
• Be aware of emission compliance, confirming the system respects Euro 6 standards and includes necessary catalytic converter provisions if applicable.

Shipping and availability vary; always confirm lead times and delivery options before purchase.

What sets Armytrix apart from the competition ?

Armytrix is renowned for its innovative valve control technology which offers fully adjustable remote control of exhaust valves, enabling drivers to customize exhaust flow and sound modes quickly and easily.

Do race / track / sport modes leave the exhaust valves open ?

Despite the name, these modes do not keep the valves permanently open; rather, they adjust valve operation dynamically to balance sound, performance, and legal noise limits depending on driving conditions.

• Remote operated valves allow manual override with an app or button.
• Valve positions adjust automatically based on RPM and demand.
• System maintains factory-like refinement when valves close.

This technology offers a refined yet sporty experience optimized for the driver’s preference.

The exhaust system significantly influences engine performance and acoustic output through:

• Improved exhaust flow reducing backpressure to increase horsepower and torque.
• Enhanced sound quality, providing a sportier exhaust note especially in AMG or valvetronic systems.
• Optimized pipe diameter and muffler design for balanced airflow and noise control.
• Better heat dispersion and durability through stainless steel construction.

The right system increases responsiveness and driving enjoyment while maintaining factory compliance and emissions standards.
