BMW G82/G83 M4 Valved Titanium Alloy Catback Exhaust System – OEM+ Straight-Piped Upgrade | Loud, Crackles & Pops | Fits G82 Coupe and G83 Convertible M4 & Competition Models (S58 Engine)

BMW G82 Coupe and G83 Convertible M4 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 M4 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.
