BMW G80/G81 M3 Valved Titanium Alloy Catback Exhaust System – OEM+ Straight-Piped Upgrade | Loud, Crackles & Pops | Fits G80 Sedan and G81 Touring M3 & Competition Models (S58 Engine)

BMW G80 Sedan and G81 Touring M3 Titanium Valved Catback Exhaust System – Purple Heat-Treated Finish | OEM+ Performance Upgrade

Unleash your S58’s true potential.

Add a menacing yet refined flair to your BMW G8X M3 with our purple heat-treated titanium valved catback exhaust system. Featuring switchback valves controlled by an included remote, you can silence your exhaust at will — or unleash raw, aggressive sound with the click of a button. Designed for both daily driving and track performance, this system perfectly blends OEM+ sophistication with uncompromising performance.

Engineered for the S58 Powerhouse

The BMW S58 engine is one of the most advanced and performance-driven powerplants ever produced — a twin-turbocharged inline-six built for relentless power, precision, and durability.

Paired with multiple radiators and intercoolers working in harmony, it delivers staggering horsepower and torque figures.

To truly awaken its potential, a free-flowing straight-pipe titanium catback exhaust is one of the most transformative upgrades you can make. Unlike conventional stainless-steel systems, titanium drastically reduces weight, improves exhaust velocity, and introduces a sharper, more exotic tone that perfectly complements the S58’s turbocharged aggression.

Sound & Performance Benefits

Experience the best of both worlds:

• Valved Control System: Instantly toggle between a refined, quiet cruise or an all-out roar filled with crackles and pops — all from the included remote.
• True Dual Exhaust Layout: A true dual-pipe design from the headers back eliminates restrictive crossovers for optimal flow and power gains.
• Enhanced Tone: Exotic resonance at low RPMs and a crisp, high-rev scream — no rasp, no drone, just pure S58 symphony.
• Tunable Performance: Pairing with a custom tune can further unlock horsepower by reducing backpressure and maximizing exhaust efficiency.

Why Titanium Over Stainless Steel

Titanium represents the pinnacle of exhaust engineering. It’s over 40% lighter than stainless steel, delivering noticeable improvements in throttle response, handling, and weight balance.

Its heat-dissipating properties drastically reduce under-hood temperatures, protecting sensitive components and preserving performance during spirited or track driving.

And unlike stainless systems that can dull over time, titanium’s distinct heat-treated coloration only becomes richer — showcasing blues, purples, and golds that tell the story of heat, power, and precision.

Beyond aesthetics, titanium produces a distinctly refined acoustic profile — crisp, metallic, and exotic — offering an unmistakable race-car tone that stainless simply can’t replicate.

Premium Titanium Construction

• Aerospace-Grade Alloy: Provides exceptional strength-to-weight ratio, sound clarity, and corrosion resistance.
• Purple Heat-Treatment: Each system is meticulously heat-treated to achieve a stunning gradient finish while enhancing thermal resistance.
• Superior Sound Quality: Titanium offers a balanced blend of aggression and clarity — never tinny like cheap metals or boomy like low-grade steel.
• Thermal Efficiency: Rapid heat dissipation improves long-term reliability and ensures consistent performance.

Complete OEM+ Installation Kit

Everything you need is included for a seamless, bolt-on installation — no last-minute trips to the parts store.

• Heat-treated exhaust tips (anti-flaking & crack-resistant)
• Valved remote control system with wiring harness

Your G8X should sound as fierce as it performs — and look every bit as stunning.

FITMENT: G80 Sedan and G81 Touring M3 including Competition Models.

IMPORTANT NOTE: All exhaust systems are custom fabricated to order. These are not generic third-party exhausts — our team handles each system in-house, and you’ll be able to see the craftsmanship immediately upon unboxing.

While materials are sourced worldwide, all final metalwork, quality assurance testing, and fitment/mounting verification are completed at our facility in Texas, United States.

Because of the extensive labor involved and the high cost/risk of return shipping exhaust systems, full returns are not accepted. However, if there is ever a verified fitment issue, we will 100% stand by our guarantee and, with proper documentation, make sure you are taken care of.

Please note: once an order is placed, if we are not contacted within 24–48 hours of order placement, cancellations cannot be promised.

Each exhaust unit takes approximately 2–3 weeks for full fabrication. Once fabrication is complete and the system is in quality assurance testing, we will send detailed photos of your exhaust for you to review and approve so you feel fully confident before it ships.

Please refer to the “Fitment” section in the product description for compatibility details.
