BMW G80/G82/G87, M3/M4/M2 Titanium Valved Z Pipe Catback Exhaust

The ultimate exhaust for the BMW G80 M3, G82 M4 and G87 M2. A full titanium valved system from the downpipes back, with an equal-length Z pipe mid section, a valved rear muffler, carbon fibre tips and the wireless valve remote kit supplied.

Designed specifically for the twin-turbocharged S58, it delivers an exotic, race-inspired note while dramatically reducing weight. The equal-length Z pipe balances flow from both turbochargers before the muffler, giving a smoother, fuller tone underneath the sharp titanium top end.

Crafted from aerospace-grade titanium with precision TIG welding, hand heat-anodised in your choice of Blue, Purple or Gold, and supplied complete with the valve remote kit and all hardware.

Key Features

Full Titanium Construction

Manufactured from high-grade titanium for exceptional strength, corrosion resistance and substantial weight savings over both the factory and stainless steel systems.

Equal-Length Z Pipe Mid Section

Both turbochargers feed matched-length pipes, balancing pulses for a smoother, fuller exhaust note and consistent flow.

Integrated Valved Exhaust System

Electronically controlled valves switch between a refined OEM+ sound and a fully open, race-inspired exhaust tone, controlled from the supplied wireless remote.

Carbon Fibre Tips

Quad carbon fibre tips finish the rear of the car. If you would prefer Black or Chrome Style Exhaust Tips, please contact our store after your purchase and we can arrange your preferred exhaust tip option.

Signature Titanium Exhaust Note

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

Direct Bolt-On Fitment

Designed specifically for the G80, G82 and G87 using factory mounting locations for straightforward installation.

Choose Your Titanium Finish

The colour on a titanium exhaust is produced by heat, not by paint or coating, and it runs through the pipework and muffler body as one continuous finish. Three options are available:

Blue - the finish shown in our photography. Deep blue through the piping with gold and violet heat banding across the bends and weld lines.

Purple - rich purple and magenta across the system with bronze shading over the muffler body.

Gold - warm bronze and gold dominant, with blue and violet coming through at the bends and weld lines.

Because the finish is created by heat, no two systems are identical and the banding will vary slightly from the photographs. That variation is characteristic of anodised titanium rather than a fault.

Performance Benefits

When paired with supporting modifications and tuning, this exhaust system can provide:

• Significant weight reduction over the factory exhaust
• Faster turbo spool and improved throttle response
• Increased exhaust flow and reduced backpressure
• A sharper, louder and more aggressive exhaust tone
• Enhanced high-RPM sound and driving engagement

Performance gains may vary depending on supporting modifications and tuning.

Which OPF Option Do I Need?

European-delivered cars are fitted with a particulate filter (OPF/GPF) in the exhaust. Australian and North American cars are not. The two specifications use different exhaust hardware, so choosing correctly ensures a precise, bolt-on fit.

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.
