BMW F90 M5 Titanium Valved Catback Exhaust

BMW F90 M5 Titanium Valved Catback Exhaust

This is the definitive exhaust upgrade for the BMW F90 M5, a full titanium valved catback system that transforms both the sound and the weight of the car in a way no stainless system can match.

Titanium is dramatically lighter than stainless steel, and on a system this size that saving is significant, taken directly from the rear of the car where it matters most for balance. It also produces a distinctly sharper, harder edged exhaust note, the sound associated with factory motorsport systems.

An independent Varex valve system, controlled by remote, gives complete authority over the volume. Closed, the car stays civilised for daily use. Open, the S63 is given a genuinely ferocious voice.

The system is finished in the burnt titanium tone that develops naturally through the material, with precision TIG welding throughout and factory mounting points retained for a clean bolt on installation.

For an owner who wants the F90 to sound and feel like the flagship it is, this is the system to fit.

Key Features

Independent Varex Valve System

Rather than reusing the restricted factory valves, this system operates its own dedicated valve assembly with complete travel in both directions. Sealed when closed for quiet running, and fully unobstructed when open for maximum flow and volume. Switch between a refined daily-driving experience and an aggressive performance exhaust note at the touch of a button.

Full Titanium Construction

Genuine titanium throughout, delivering a substantial weight saving over stainless steel from the rear of the vehicle.

Sharper Titanium Exhaust Note

Titanium produces a harder, more metallic and more aggressive tone than stainless steel, closer to a factory motorsport system.

Burnt Titanium Finish

The heat treated finish characteristic of the material, giving the system a distinctive appearance under the car and at the tips.

Precision TIG Welded

Titanium demands exacting weld control, and every joint is executed to withstand sustained extreme exhaust gas temperatures.

Mandrel Bent Tubing

Consistent internal diameter through every bend so exhaust flow is never restricted.

Direct Bolt On Fitment

Designed specifically for the F90 M5 using the factory mounting locations and hanger positions.

Please Note

Professional installation is strongly recommended.

Titanium develops a natural variation in colour through heat cycling. This is characteristic of the material and not a defect.

Exhaust sound characteristics may vary depending on supporting modifications such as downpipes and ECU tuning.
