Bull-X 2.25″ replacement pipes for Audi S4/S5 B9 260 kW (354 PS)

Bull-X replacement pipes for the Audi S4 B9 and S5 B9 exhaust systems allow the original pre-silencers to be removed. The original pre-silencers can be refitted if required.

• Material: stainless steel
• Replaces the pre-silencer
• Without approval
• Pipe diameter: 2.25″ / 60 mm

Note: The original pre-silencer pipes must be separated or cut while fitted to the vehicle for removal and refitting. They therefore cannot be removed as a complete assembly.

Road use: These replacement pipes do not have road approval and are intended exclusively for track use. Legal use on public roads requires an exhaust system with ECE approval together with an EG-approved catalytic converter; other catalytic-converter combinations are intended for track use only.

Suitable for: Audi S4 VIII (B9), Audi S5 II (B9).
