Audi B9/B9.5, RS4/RS5 Titanium Mid Pipe

Audi B9/B9.5 RS4/RS5 Titanium Mid Pipe

This full titanium mid pipe replaces the heavily silenced factory centre section of the Audi RS4 or RS5, removing the last major restriction in the exhaust while taking meaningful weight out of the middle of the car.

Titanium is dramatically lighter than stainless steel, and on a section this size the saving is real. It also changes the character of the sound, producing a harder, more metallic edge that suits the 2.9L twin-turbo V6 far better than the muted factory pipework.

The straight-through design removes the factory centre silencer entirely, allowing exhaust gas to move freely between the downpipes and the rear section. Paired with the factory rear exhaust it transforms the volume and tone; paired with downpipes and a catback it completes the system.

Finished in the blue burnt titanium tone that develops naturally through heat treatment, with high temperature TIG welding throughout and factory mounting points retained for a direct bolt on installation.

For an owner building the RS4 or RS5 properly rather than chasing volume alone, this is the component that does both jobs at once.

Key Features

Full Titanium Construction

Genuine titanium alloy throughout, delivering a substantial weight saving over the factory stainless centre section.

Sharper Titanium Exhaust Note

Titanium produces a harder, more metallic tone than stainless steel, giving the twin-turbo V6 a genuine motorsport character.

Straight Through Design

Removes the restrictive factory centre silencer entirely for unrestricted flow between the downpipes and the rear section.

Blue Burnt Titanium Finish

The distinctive colouring that develops naturally through heat treatment, characteristic of the material.

High Temperature TIG Welding

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

Direct Bolt On Fitment

Uses the factory mounting points and clamp positions, with no cutting or welding required.

Performance Benefits

• Significant weight reduction over the factory stainless centre section
• Removes the restrictive factory centre silencer
• Increased exhaust flow efficiency
• Sharper throttle response
• Harder edged, more aggressive twin-turbo V6 tone
• Completes the exhaust path when paired with downpipes and a catback

Performance gains may vary depending on ECU calibration and supporting modifications.

Please Note

Professional installation is strongly recommended.

This is a mid pipe section only. Downpipes and the rear exhaust section are not included.

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

Removing factory silencing will increase cabin noise. Sound characteristics vary considerably depending on which other exhaust components are fitted.
