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.
