Valvetronic Designs BMW Downpipes

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

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.
