Milltek Sport Audi RS5 B9 2.9 V6 Turbo Coupe Cat Replacement Pipes

Milltek Sport's Cat Replacement Pipes for the Audi RS5 (B9) 2.9 V6 Turbo Coupe replace the factory catalytic converters with straight-through stainless steel pipes, delivering maximum flow through this section of the exhaust system. This is the most extreme option available for this particular section of the exhaust, removing catalytic function entirely rather than the more moderate approach of a higher-flow sports cat.

Constructed from T-304 stainless steel throughout, these pipes are built for long-term durability, resisting the corrosion that eventually catches up with mild steel factory parts. Intended primarily for track and off-road use, worth checking local emissions regulations before fitting to a road car, since removing catalytic converter function entirely will affect emissions compliance in most regions.

Why Choose These Cat Replacement Pipes

• Maximum flow through this section, the most extreme option available for this platform
• T-304 stainless steel construction throughout, built for long-term durability
• Genuinely lets this twin-turbo V6 breathe with the least restriction possible
