Bull-X Downpipe Audi A4, A5 B9 2.0TFSI

This Bull-X downpipe for Audi A4 B9 or A5 B9 with a 2.0 TFSI engine is a high-quality downpipe that will increase your car's power, torque and sound. The downpipe is a replacement for the original downpipe for the Audi A4 or A5 B9. Because this downpipe has a larger diameter (89 mm tapering to 76 mm) than the original, exhaust gases are discharged more quickly at the turbo. This not only has the advantage of increasing power, but also means that the turbo encounters less resistance. This benefits the service life of the turbo.

• Made in Germany
• Manufactured from high-quality T304 stainless steel
• Handcrafted (TIG welded)
• Diameter of 3.5 inches (89 mm) tapering to 3 inches (76 mm) at the flange
• Provides an increase in torque (Nm) and power (hp)
• Increased throttle response
• Uses the original dimensions for attachment to the flange. This means that no adapters or similar items are required for installation.

Suitable for both Quattro and front-wheel drive models.

Larger diameter for better flow
The original downpipe has a small diameter after the catalytic converter. This causes some of the power (horsepower) and torque (Nm) to be lost. This downpipe from Bull-X solves this problem by using a diameter of 89 mm (3.5 inches). This downpipe also has a smoother shape, which improves the flow of exhaust gases. This ensures that the exhaust gases can be discharged more quickly to the turbo.
