CTS Turbo 4" Race Downpipe for BMW N20 4-cylinder (2012-2017) F20-F21-F22-F30-F32-F36

The CTS Turbo 4-inch race downpipe delivers maximum exhaust flow for BMW's N20 turbocharged four-cylinder engine. Engineered for F-chassis 228i, 328i and 528i models from 2012 to 2017, this race-spec component eliminates the restrictive factory catalytic converter to reduce backpressure and improve turbo efficiency. Precision mandrel-bent construction ensures smooth gas flow throughout the larger diameter pipework. Designed for track-focused applications where emission compliance isn't required, this downpipe suits tuned N20 engines demanding unrestricted exhaust capacity. Professional installation recommended for proper fitment across F20, F21, F22, F30, F32 and F36 chassis variants.
