KYOSTAR Catless Downpipe for BMW F20 F22 F30 F31 F32 F36 G20 G30 B46 2.0T

The KYOSTAR Catless Downpipe is designed for BMW B46 2.0T turbocharged applications, including F-Series and G-Series models. Featuring a high-flow catless design, this downpipe improves exhaust flow efficiency, reduces factory backpressure, and helps enhance turbo response for modified BMW vehicles.

Manufactured with precision welded stainless steel construction, this downpipe provides improved exhaust pulse flow and a more aggressive exhaust tone compared with the restrictive factory unit. The integrated O2 sensor port and factory-style mounting points ensure proper installation for compatible B46 engine platforms.
