The M340i doesn’t just need more sound—it deserves it. Our valved stainless catback unlocks the full voice of the B58: deeper, sharper, and way more aggressive than stock. Valves open? It’s a straight-up riot. Closed? Civil enough for cold starts and commutes. Crafted from T304 stainless steel and designed using full 3D scans, this system fits like OEM but hits way harder. Clean sound. Zero drone. Full attitude.
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
