RENNVOX VALVED EXHAUST SYSTEM WITH SINGLE MID PIPE & EXHAUST TIPS FOR BMW G8X M3 & M4

Transform the Sound and Performance of Your BMW G8X M3 or M4

Experience the full potential of your BMW G8X M3 or M4 with the RENNVOX Valved Exhaust System with Single Mid Pipe & Exhaust Tips. Engineered specifically for the BMW S58 twin-turbocharged inline-six engine, this premium exhaust system delivers a more aggressive exhaust note, improved exhaust flow, reduced back pressure and enhanced throttle response while retaining everyday drivability through an electronically controlled valve system.

Developed and tested by EMS Carparts, the RENNVOX exhaust has been engineered to complement the exceptional performance of the latest BMW M platform. Whether you're driving on the road, enjoying spirited mountain drives or attending track days, this system provides an engaging exhaust note without unwanted cabin drone.

Engineered Specifically for the BMW G8X Platform

The factory exhaust system on the BMW G80 M3 and G82/G83 M4 is designed to satisfy global noise and emissions regulations. While effective, the standard system mutes much of the S58 engine's character. The RENNVOX Valved Exhaust System unlocks a deeper, more purposeful exhaust tone while improving overall exhaust gas flow.

The single mid pipe configuration replaces the restrictive factory dual mid-pipe arrangement, creating smoother exhaust flow and delivering a more authentic inline-six performance sound. Combined with precision-engineered rear silencers and electronically controlled exhaust valves, the system provides the perfect balance between refined cruising and an aggressive performance soundtrack when required.

Electronically Controlled Valve Technology

The integrated electronic valve system allows the exhaust to adapt to every driving situation.

• Valves Closed – Refined, comfortable sound ideal for daily driving and highway cruising.
• Valves Open – Maximum exhaust flow with a deeper, louder and more aggressive BMW M exhaust note.
• Compatible with the vehicle's factory drive modes and valve operation.

Single Mid Pipe Design

Unlike the factory twin mid-pipe arrangement, the RENNVOX single mid pipe optimises exhaust pulse scavenging and improves overall gas flow. The result is:

• Reduced exhaust restriction
• Lower back pressure
• Improved throttle response
• Enhanced turbocharger efficiency
• Sharper engine response throughout the rev range
• A smoother, richer inline-six exhaust tone

Premium Stainless Steel Construction

Manufactured from premium-grade T304 stainless steel, every RENNVOX exhaust system is designed to withstand extreme temperatures and harsh driving conditions while maintaining its appearance for years to come.

• T304 stainless steel construction
• Precision CNC mandrel bent tubing
• TIG welded for maximum strength

Performance Benefits

Optimising exhaust flow allows the S58 engine to breathe more efficiently, helping improve performance and responsiveness.

Exhaust Sound

The RENNVOX Valved Exhaust System has been carefully tuned to deliver the sound expected from BMW's flagship M models. At low engine speeds the exhaust remains refined and comfortable, while opening the valves transforms the character of the S58 engine into a deep, aggressive and unmistakably performance-focused soundtrack with enhanced crackles and overrun when appropriate.
