BMW F90 M5 Valved Cat-Back Exhaust System

Grade 5 Titanium, 3.0" Tubing, Large Cross-Section X-Pipe, Electronic Valves


Overview

The F90 M5 carries on the S63 4.4L twin-turbo legacy—but its factory exhaust leaves the soundtrack on mute. The Valvetronic Designs Valved Titanium Cat-Back unlocks the voice this car deserves: refined when you want it, ferocious when you don’t.

Built from Grade 5 titanium with 3.0" tubing from inlet to outlet, the system integrates seamlessly with factory control or runs on a standalone remote for full command in any drive mode. Finish it with your choice of premium tips and let the M5 sing.


Why It Works

  • Forward, Large Cross-Section X-Pipe: Increases scavenging, smooths tone, and virtually eliminates unwanted rasp—especially on cars with aftermarket downpipes.

  • 3.0" Free-Flow Architecture: Reduces back pressure for sharper throttle response and a cleaner top-end note.

  • Valved Control, Your Way: Tie into the car’s ECU (Sport/Sport+) or use the included standalone remote for instant open/close in any mode.


Sound & Control

  • Valves Open: Deep, exotic V8 character with crisp overrun and engaging burbles—without the buzzy, raspy edge common on other setups.

  • Valves Closed: Subtle, composed tone for daily commuting and highway cruising.

  • Flexible Integration: Choose factory valve integration or standalone remote control.


Construction & Options

  • Material: Ultra-light Grade 5 titanium throughout.

  • Weight Savings: 56.5 lb lighter than the factory exhaust.

  • Craftsmanship: Precision TIG welds and smooth, high-flow routing.

  • Tips: Multiple finishes available to complement your M5.


Fitment

  • 2018–2023 BMW M5 (F90)


Installation Notes

  • Direct bolt-on cat-back replacement to OEM mounting points.

  • 100% reversible—return to stock at any time.

ECU tuning is the process of adjusting the engine control unit's software to enhance vehicle performance, efficiency, or fuel economy.

It can, depending on the manufacturer. Many warranties do not cover modifications like ECU tuning.

Use the highest octane fuel recommended for your specific tune to ensure optimal performance and safety.

Yes, a properly tuned car can be used daily, as long as the tune is tailored for reliable, everyday driving.

CPC (Central Powertrain Controller) and TCU (Transmission Control Unit) manage your vehicle's powertrain and transmission systems, respectively.

Map switching allows you to change between different tuning settings (maps) for varying driving conditions without having to retune the ECU.

Yes, if done by a professional using proper tools, ECU tuning is generally safe for your vehicle.

ECU tuning works by modifying the software that controls engine parameters like fuel mixture, ignition timing, and boost pressure to optimize performance.

The process of installing a tune depends on the vehicle’s make and model. Some tunes are installed by connecting a tuning device to your car’s OBD-II port and uploading the tuned software, others may require ECU unlock.

Stage 1 is for vehicles with no modifications, stage 2 is for vehicles with bolt-on upgrades or downpipes installed.

We offer post-installation support, troubleshooting, and guidance on using your tuning software and hardware.

Choose tuning software that is compatible with your vehicle, has good reviews, and suits your performance goals (e.g., reliability vs. max power).
