CTS Turbo 4″ Catless Downpipe for BMW N20 4-Cylinder (2012-2017) F20 F21 F22 F30 F32 F36

CTS Turbo is proud to announce a catless downpipe for F-series BWM 4 cylinder N20 engines.

By removing the factory catalytic converter, you will free up exhaust flow and thus increase power and sound of the engine. Faster turbo spool and less backpressure means the car will feel more responsive and more fun to drive.

Proper tuning by Bootmod3 must be used to remove CEL and ensure proper operation.

Features:

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

This part is for off-road race use only! Not for N26 engines. Check the sticker under the hood; you have N20 engine it will say ULEV.  If it is an N26 engine, it will say SULEV.
