Active Autowerke presents catted downpipes designed specifically for BMW F90 M5, M8, X5M, and X6M models equipped with the S63TU engine. These downpipes address the restrictive nature of the factory components to enhance exhaust flow and performance.
- Manufactured in-house from 304 stainless steel with TIG welds for durability and precise fitment.
- Features a factory-matched 3.5" V-band inlet with a tapered, mandrel-bent body.
- Includes the lower section commonly referenced as the mid-pipe, streamlining the exhaust pathway.
- Equipped with a pair of 4.5" high-flow GESI catalytic converters that maintain emissions compliance without triggering a check engine light.
- Allows use of the OEM O2 sensor heat shield to preserve a stock engine bay appearance.
- GESI UHO converters are made from full 304 stainless steel and are EPA registered for 49 states (not CARB compliant).
These downpipes reduce back-pressure and radiant heat compared to the stock units, contributing to improved turbo spool and overall engine responsiveness within the designed performance parameters. Note that these catalytic converters are not legal for use in California due to state regulations.
Specifications:
- Part Type: Downpipes
- Fitment Spec: Vehicle Specific (BMW F90 M5, M8, X5M, X6M)
