Audi R8 Type 4S Titanium Valved Exhaust

The ultimate exhaust for the Audi R8 Type 4S. A full titanium valved system built around the naturally aspirated 5.2-litre V10 - designed to cut weight from the rear of the car, free up flow and give the V10 the exotic, high-revving voice it deserves.

Both banks run through a sculpted figure-eight crossover section before the rear muffler, braced by a laser-cut Proven Performance Parts plate, then out through valved outlets. With the valves closed the car stays civil on the road; open them and the V10 delivers a sharper, louder and far more dramatic note all the way to the limiter.

Crafted from aerospace-grade titanium with precision TIG welding throughout, V-band inlet connections and hand heat-anodised in your choice of Blue, Purple or Gold.

Key Features

Full Titanium Construction

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

Figure-Eight Crossover Design

The pipework from each bank loops through a sculpted figure-eight section, braced by a laser-cut Proven Performance Parts plate, for a balanced, layered V10 tone.

Integrated Valved Outlets

Valves on each side switch between a refined cruising note and a fully open, race-inspired sound.

V-Band Connections

Precision V-band flanges at the inlets for a leak-free seal that is simple to fit and remove.

Signature Titanium Exhaust Note

A sharper, higher-pitched and more exotic tone unique to titanium, with enhanced high-RPM sound - made for a V10 that revs past 8,000rpm.

Direct Bolt-On Fitment

Designed specifically for the R8 Type 4S using factory mounting locations, with no cutting required.

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 silver heat banding across every bend and weld line, and a natural titanium muffler body shading to gold and violet.

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
• Increased exhaust flow and reduced backpressure
• Sharper throttle response across the rev range
• A louder, more exotic and more aggressive V10 tone
• Enhanced high-RPM sound and driving engagement

Performance gains may vary depending on supporting modifications and tuning.
