CTS TURBO | 4″ Catless Downpipe Bmw N20 F20-F21-F22-F30-F32-F36

CTS Turbo – BMW N20 F-Series 4″ Catless Downpipe

Description

The CTS Turbo 4″ catless downpipe (part# CTS-EXH-DP-0020) is designed for BMW F-series 4-cylinder N20 engines (F20, F21, F22, F30, F32, F36). By removing the factory catalytic converter, this downpipe frees up exhaust flow, speeds up turbo spool, and reduces backpressure, making the car feel more responsive and more fun to drive. The CNC machined flange and direct-fit bracket ensure a precise bolt-on installation. Fully constructed from stainless steel and 100% TIG welded for maximum durability. Delivers power gains of 25–35 HP with a stage 2 tune (octane dependent). Produces an aggressive, race-inspired exhaust note. Note: compatible with N20 engines only — not compatible with N26. For off-road race use only. See Application Section for detailed fitment.
