CTS Turbo High Flow Catted Downpipes BMW G80/G82 M3/M4 S58 3.0T

Precision engineered for the S58. Built to improve flow, response, and sound.

Unlock the potential of your BMW S58 with the CTS Turbo High Flow Catted Downpipes, engineered specifically for the G80 M3 and G82 M4. Designed to reduce exhaust flow restriction while retaining high flow catalytic converters, these downpipes provide a more efficient path for exhaust gases and help the S58 breathe more freely.

Constructed from durable 304 stainless steel, the CTS Turbo downpipes feature a precision engineered 3 inch (76mm) design, laser cut flanges, and factory style O2 sensor placement for a clean and accurate installation.

The result is improved turbocharger spool, sharper transient boost response, increased performance potential, and a deeper, more aggressive exhaust note that brings the S58 to life. When paired with appropriate tuning, these downpipes can complement a Stage 2 performance setup.
