Precision-engineered. Purposefully tuned. Pure BMW soul.

The Yonristic Performance Original Exhaust System for the BMW G80 M3 and G82 M4 is designed for purists who want the full symphony of the S58 engine—without compromise. Built with a true dual 3.0-inch mandrel-bent layout and an aggressive X-pipe configuration, this system maximizes flow, enhances power delivery, and sharpens tone across the RPM range.

At its heart, the system blends power with precision, thanks to our signature crossflow X-pipe. This layout balances exhaust pulses between banks, removing unwanted drone and unlocking a refined but aggressive exhaust note. The result? Crisp start-ups, exotic WOT tone, and an engaging sound even during casual driving.

The system supports two valve modes:

• Factory Plug-and-Play OEM Valves – seamlessly integrates with factory drive modes

• Yonristic Remote Valve Control – full manual override, 100% open-on-command

Whether you're leaving your neighborhood or arriving at the track, your sound is under control.

Crafted in TIG-welded 304 stainless steel or optional Grade 5 titanium, every system is tested for maximum durability and optimal fitment. Quad 4.5” tips in black ceramic-coated stainless, brushed, or titanium blue complete the look.

Exceptional Performance Boost

The BMW G80 G82 M3 M4 Exhaust system is designed to significantly enhance your vehicle's performance. This catback exhaust utilizes improved flow dynamics, optimizing exhaust gas exit to reduce back pressure.

So, whether you crave attention on the streets or a peaceful drive, this exhaust system adapts to your needs.
