DESCRIPTION
Want more power without ditching emissions control?
WSTN Performance 200 Cell Catted Downpipes are designed specifically for BMW’s M2/M3/M4 models with the S58 3.0L twin-turbo powered engines. These high-flow, street-friendly downpipes replace the factory catalytic converter with a 200-cell motorsport-grade unit, unlocking turbo response and performance while retaining a refined tone and daily drivability.
Built from full stainless steel and wrapped in OEM-style heat shielding, this unit delivers track-ready gains without triggering check-engine lights when paired with proper tuning.
Why Upgrade?
✅ 200 Cell High-Flow Catalyst – Maximum flow with emissions balance
✅ Stainless Steel Construction – Full corrosion and heat resistance
✅ OEM-style Thermal Shielding – Keeps engine bay temps under control
✅ Mandrel-Bent Piping – Smooth, unrestricted exhaust flow
✅ CNC Flanges & TIG Welds – Precision fitment and durability
✅ No CEL with Tune – Compatible with Stage 2+ tuning platforms
