Extract maximum performance from your BMW with the German Car Accessories (GCA) Performance N55 EWG Downpipe, engineered specifically for the 2013-2018 BMW M135i F20/F21 equipped with the 3.0L Turbocharged N55 inline-six engine featuring the Electronic Wastegate (EWG) turbocharger.
Designed by German Car Accessories, also known as GCA, under our GCA Performance product line, this high-flow downpipe replaces the restrictive factory unit to significantly improve exhaust flow directly from the turbocharger. By reducing exhaust back pressure, it allows the turbocharger to spool faster, improves throttle response, delivers stronger mid-range acceleration, and increases horsepower and torque potential when paired with ECU tuning and other supporting performance modifications.
Manufactured from high-quality T304 stainless steel, this downpipe is engineered to withstand extreme exhaust temperatures while providing exceptional corrosion resistance and long-lasting durability. Smooth mandrel-bent tubing maximizes exhaust gas flow, while precision TIG welds ensure outstanding strength, reliability, and OEM-quality fitment.
Designed as a direct bolt-on replacement, this downpipe installs using the factory mounting locations without permanent modifications. The fully reversible design allows you to return your vehicle to its original factory configuration whenever necessary.
Every German Car Accessories performance product is backed by our 1-Year Warranty for complete confidence and peace of mind.
