The M550i hides a beast—this system sets it free. Our valved stainless steel catback unlocks deep tone, sharp volume, and a more visceral V8 sound that transforms every drive. Crack the valves open, and you get the full symphony: rich, loud, and unmistakably angry. Close them, and the tone softens for a calm commute or cold start. TIG welded from T304 stainless steel and designed using full 3D scans for a precise OEM+ fit. Daily-driver friendly. Chaos approved.
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
- Comes standard with a free HOA violation
