Redstar Catless Downpipe - Mercedes CLA45 / A45 / GLA45 M139

The Redstar catless downpipe is specifically engineered for M139-powered Mercedes A45 W176, CLA45 C117 and GLA45 X156 models. Eliminating the restrictive factory catalytic converter, this downpipe dramatically improves exhaust gas flow and reduces backpressure throughout the rev range. Constructed from mandrel-bent pipework, it provides a direct OEM replacement fitment while unlocking substantial performance gains when paired with ECU tuning. Essential for extracting maximum potential from modified M139 engines, this downpipe delivers sharper throttle response and an aggressive exhaust note that matches the platform's performance credentials.
