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.
