BMW F91/F92/F93 M8 Titanium Valved Catback Exhaust

BMW F91/F92/F93 M8 Titanium Valved Catback Exhaust

Transform the sound, performance and driving experience of your BMW M8 with this premium Full Titanium Valved Catback Exhaust System — engineered for enthusiasts seeking maximum performance, aggressive acoustics, and significant weight reduction.

Designed specifically for the F91, F92 and F93 M8 equipped with the 4.4L twin-turbocharged S63 V8, this full titanium system replaces the restrictive factory rear section with a high-flow mandrel-bent titanium design. Whether cruising with the valves closed or unleashing the full sound with the valves open, it offers the perfect combination of everyday refinement and motorsport character.

Crafted from lightweight aerospace-grade titanium with precision TIG-welded construction, this exhaust system is built to withstand extreme temperatures and high-performance driving conditions while delivering a premium finish and an unmistakable titanium tone. The burnt titanium finish and quad carbon fibre tips make it as distinctive to look at as it is to hear.

Whether paired with the factory downpipes or upgraded high-flow or catless downpipes, it delivers improved throttle response, enhanced turbo acoustics, and a significantly more engaging drive.

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 a quieter OEM+ driving experience, and fully unobstructed when open for a fully aggressive exhaust tone.

Full Titanium Construction

Manufactured from high-grade titanium for exceptional strength, corrosion resistance, and substantial weight savings compared to factory and stainless steel exhaust systems.

Optimised Exhaust Flow

Mandrel-bent titanium piping and a high-flow design reduce exhaust restriction, improving turbo efficiency and throttle response.

Signature Titanium Exhaust Note

Produces a sharper, higher-pitched and more exotic tone unique to titanium exhaust systems, with enhanced crackles, pops and high-RPM sound.

Precision TIG Welded

Professionally TIG welded for superior durability, strength and premium craftsmanship throughout the system.

Remote Controlled Operation

Valve operation is handled entirely by the supplied remote. The system does not connect to the factory valve motors.

Direct Bolt-On Fitment

Built to the correct specification for your body style using factory mounting locations for straightforward installation.

Which OPF Option Do I Need?

NON OPF - AU/US SPEC — for vehicles delivered new in Australia, New Zealand, the United States or Canada.

OPF EQUIPPED - EU SPEC — for vehicles delivered new in the European Union or the United Kingdom.

UNSURE - CONTACT US — select this and our team will confirm the correct specification against your VIN before dispatch.
