🏎️ BMW F90 M5 VALVED TITANIUM CAT-BACK EXHAUST SYSTEM | PISTON TWISTIN

The BMW F90 M5 carries the legendary 4.4L twin-turbo S63 powerplant — but its factory exhaust fails to match its potential. The Valvetronic Designs Valved Titanium Cat-Back System unleashes the true personality of the M5, combining race-grade titanium construction, intelligent valve control, and a large cross-section X-pipe for a perfect balance of aggression and refinement.

Refined when you want it. Ferocious when you don’t.

⚙️ WHY IT WORKS

• Forward Large Cross-Section X-Pipe: Enhances scavenging, smooths tone, and removes rasp — especially when paired with free-flow downpipes.

• 3.0" Free-Flow Architecture: Improves exhaust velocity, reduces back pressure, and sharpens throttle response.

• Valved Control, Your Way: Integrates directly with the car’s OEM valve control (Sport/Sport+) or operates via standalone remote for full manual control in any drive mode.

This is not just an exhaust — it’s a complete transformation of sound, power, and driving experience.

🔊 SOUND & CONTROL

• Valves Open: Deep, exotic V8 tone with sharp overrun pops and rich, aggressive character — without the harsh rasp or drone found on lesser systems.

• Valves Closed: Smooth, subtle tone ideal for long highway drives, commuting, or early-morning starts.

• Flexible Integration: Choose between OEM-style electronic control or the included remote for instant open/close functionality.

🧱 CONSTRUCTION & CRAFTSMANSHIP

• Material: Aerospace-grade Grade 5 Titanium for extreme strength and ultra-light weight

• Tubing: Full 3.0” mandrel-bent titanium from inlet to outlet

• Weight Savings: A massive 56.5 lbs lighter than the factory exhaust

• X-Pipe Design: Forward-mounted, large cross-section for refined tone and efficient scavenging

• Craftsmanship: Precision TIG welds, smooth transitions, and mirror-finished details

• Tips: Available in multiple finishes — brushed titanium, burnt blue, black chrome, or carbon fiber — to match your M5’s personality
