Exhaust Mercedes CLA-Class C117 (2013-2019)

The OEM exhaust systems for the Mercedes CLA Coupé (C117) and Shooting Brake (X117) ensure perfect compatibility and sporty style. Common features include rectangular stainless steel outlets and a dual flow design, particularly in AMG Line or Urban trims. For example, the rear exhaust with valve for the CLA 220 Coupé W117 weighs 13.749 kg, is 2.1 m long packaged, and 1.25 m wide and 16 cm high, with a volume of 0.42 m³. These systems improve performance and replace the original parts while requiring chassis verification via VIN. AMG trims like CLA 45 come with chromed outlets, red calipers, AMG Performance exhaust, and 19-inch black wheels.

Yes, numerous stainless steel aftermarket sport exhaust systems are offered for the CLA C117, typically in a cat-back configuration to comply with Euro 6 standards. Popular kits enhance sound and performance, often replacing the muffler and resonator with stainless components. For example:

• Supersprint Pack AMG Cat-Back: Complete stainless line with resonator delete for CLA 200/250 variants
• Inoxcar Sport Muffler for CLA 45 AMG enhancing rear exhaust sound
• Fox Duplex rear muffler with 2x80mm stainless outlets
• MN-Automo diffuser and chrome tips for the W117 series
• Various universal sport mufflers from Auto-Doc

Typical outlet diameters range from 65 to 70 mm.

The CLA C117 exhausts are tailored to engines compliant with Euro 6 emissions standards, covering both petrol and diesel variants:

• Petrol: M270 1.6L turbo (CLA 180/200 with 122/156 hp), M133 2.0L turbo (360/381 hp CLA 45 AMG 4MATIC)
• Diesel: OM651 2.1L turbo (CLA 220 CDI with 170/177 hp)

Exterior features such as rear diffusers, redesigned bumpers, side blades, perforated discs, and AMG Line or Sport Black packs complement these exhausts.

Owners on forums confirm factory exhaust outlet diameters around 65-70 mm. Aftermarket modifications usually amplify the exhaust sound without affecting vehicle homologation or compliance. Users recommend verifying exhaust system compatibility using the VIN or registration plate before installation. OEM replacements are straightforward to install while sportier kits generally require professional installation to ensure optimal performance and fitment.

To maintain exhaust system durability and performance:

• Use premium quality fuel suitable for your engine type
• Replace gaskets, sensors, and injectors as recommended during exhaust assembly
• Follow manufacturer instructions strictly including not starting the engine with ignition wires open or by pushing/towing
• Regularly replace spark plugs and engine oil
• Have the engine and exhaust system periodically checked by an authorized technical center

Such care prevents premature wear and ensures emissions compliance.

Valvetronic exhaust systems for the CLA-Class C117 offer dynamic sound modulation via valve control technology. These systems typically include:

• Valve control with modes for refined city driving or aggressive sporty sound
• Remote control or app-enabled valve operation
• Full stainless steel construction with enhanced flow design
• Options such as cat-back configurations with downpipes and performance mufflers

These exhausts improve the driving experience by tuning exhaust flow and sound to driver demand and RPM, without compromising stock emissions control.

Compatibility verification is essential before purchasing or installing an exhaust. To proceed:

• Provide your VIN (Vehicle Identification Number) or registration to confirm exact model and powertrain
• Consult the product documentation and manufacturer guides for sizing, connection types, and vehicle fitment
• Ensure the exhaust system matches emissions standard requirements (Euro 6 for CLA C117)
• Consider professional installation to guarantee proper valve control and sensor positioning
• Check shipping availability and conditions, as some exhausts may be shipped with tracking and free returns within specified periods if unused

Following these steps helps ensure correct purchase and installation of your Mercedes CLA-Class exhaust system.
