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

The CTS Turbo catless downpipe for F-series BMW N20 four-cylinder engines deletes the factory catalytic converter to free up exhaust flow, building power and a more aggressive sound. Less backpressure means faster turbo spool and a more responsive, more fun car. Fully TIG welded from stainless steel with a CNC-machined flange and a direct-fit bracket, it bolts right into place.

Features

• CNC-machined flange and direct-fit bracket
• Fully TIG welded stainless steel construction
• 25-35HP increase with a stage 2 tune (octane dependent)
• Aggressive sound

Proper tuning via Bootmod3 must be used to clear the CEL and ensure proper operation. Not for N26 engines — check the sticker under the hood: an N20 engine reads ULEV, while an N26 reads SULEV. Stage 2 software is required to avoid a check engine light.

Fitment (check the downpipe flange on the vehicle)
