奔驰 W176 A 220 四驱 (184 Hp) 2013 -> 2015

High performance sport exhaust for the Mercedes A 220 2.0 Turbo 4Matic (4WD)

The stock turbo downpipe with the integrated ceramic catalytic converter, fitted close to the turbochargers, is quite restrictive.
The Supersprint downpipe is a direct pipe. A specific O2 sensor cheater or a ECU tune are necessary to avoid the Check Engine Light.

The “overpipe” that passes above the front axle with the flex joint isn’t restrictive to the gas flow so it’s not necessary to replace it.

The rest of the system can be replaced entirely.
The front and centre section are available as pipe only component, for improved flow and sound.
The front pipe is also available with a high flow metallic cat by HJS motorsport, to be fitted along with the downpipe for road use, to reduce the pollutant emissions.

On cars not fitted with the "Supersport" kit, which have a resonator in the centre section, we recommend fitting centre pipe and rear muffler for optimal sound.
The front pipe avoid cutting the OEM system.
 
The rear muffler has a direct flow design, without chambers or restrictions.
 
A set of oval tailpipes for the OEM bumper is available, as well as exit pipes for the 45 AMG conversions (A45, CLA45, GLA45).
OEM 45 diffuser and tailpipes are necessary for the conversion kits.
 
The power increase for the full system is around 14hp.
