The titanium setup is for the ones who want everything—less weight, more sound, and zero compromise. Built from aerospace-grade titanium, it drops pounds and sharpens the tone into something raw and unapologetic. Our single midpipe design brings the S58 to life—amplifying that classic inline-6 growl with more volume and character across the entire rev range. Valves open? It’s unfiltered. Closed? Still civilized. Designed using 3D scans for perfect fitment, this system is lighter, louder, and made to turn every pull into a full-on event.
Features:
- Louder, more aggressive sound–with zero drone
- Single midpipe design amplifies the signature BMW inline-6 sound
- Valve-controlled chaos: violent when open, stealthy when shut
- Built from 100% Titanium 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
