BMW GEN3 B58N 400 Cell Catted Downpipes
BMW GEN3 B58– EPA-Compliant 400 Cell Catted Downpipes
Engineered for the Gen 2 B58 Turbocharged Inline-6 • High-Flow • Compliant •Â
Introducing Our NEW 400 Cell EPA-Compliant Downpipes for the GEN3 B58 Platform
The Gen 2 B58 (B58N) turbocharged inline-6 is one of BMW’s most capable modern engines, known for its immense tuning potential and smooth power delivery. However, factory catalysts restrict exhaust flow and limit turbo efficiency. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, improve turbo spool characteristics, and unlock a deeper, more aggressive exhaust tone — all while maintaining emissions compliance standards.
This upgrade lays the foundation for increased performance on both stock and tuned vehicles.
Why Upgrade to 400 Cell?
- EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
- Faster Turbo Spool: Reduced restriction enhances responsiveness and mid-range torque.
- Increased Tuning Headroom: Supports higher boost levels compared to restrictive factory catalysts.
- Enhanced Exhaust Character: Deeper tone with stronger turbo acoustics and sharper crackles.
Performance & Engineering
- Optimized Flow Architecture: Minimizes backpressure while preserving catalyst efficiency.
- Mandrel-Bent Tubing: Smooth internal transitions for maximum exhaust velocity.
- Precision TIG Welding: Built to withstand high exhaust temperatures and elevated boost pressure.
- Direct OEM Bolt-On Installation: Utilizes factory mounting locations for straightforward installation.
- Engineered to Pair Seamlessly with Valvetronic Exhaust Systems
Sound Transformation
- Stock Exhaust + Downpipes: Noticeable increase in depth and turbo presence with improved exhaust clarity.
- Valvetronic Exhaust + Downpipes: Maximum transformation — enhanced crackles, sharper turbo spool acoustics, and a more aggressive overall signature.
Construction & Durability
- Premium high-grade stainless-steel construction
- High-temperature resistant 400 cell catalyst cores
- OEM-style sensor placement for proper operation
- Engineered for long-term reliability under high boost and tuned applications
Unlock the full performance potential of your B58N — starting at the source.
