The F90 M5 is fast—but stock, it sounds like it’s holding back. This stainless catback system sets it free. Open the valves and you get the full V8 symphony: loud, deep, and aggressive without being obnoxious. Close them, and it tones down just enough for cold starts and daily use. Built from T304 stainless with TIG welds and 3D-scanned for a precise fit—this is an OEM+ system with none of the factory compromise.
Features:
- Louder, more aggressive sound–with zero drone
- Valve-controlled chaos: violent when open, stealthy when shut
- Built from 100% T304 stainless steel with pro-grade TIG welds
- Engineered using 3D scans for perfect fitment and a clean, OEM+ fit
- Direct bolt-on installation with complete hardware mounting kit
- Lighter than stock for a slight edge in performance
- Comes standard with a free HOA violation
