Exhaust Audi A4

Krosfou offers exhaust systems primarily designed for Audi A4 B5 (1994-2001), B7 (2004-2008), and B8/B8.5 (2008-2015) generations. The exhausts are compatible with common engines including 1.8T, 2.0 TFSI, and 2.0 TDI variants, ensuring a designed fit for each specific model and engine type to maintain performance and compliance.

All Audi A4 exhaust systems provided by Krosfou are manufactured 100% in stainless steel INOX 409. This stainless steel ensures high durability and corrosion resistance, suited for long-term vehicle use. The exhausts are manufactured to meet or exceed OEM standards with premium build quality.

Upgrading to a Krosfou exhaust system can provide multiple performance improvements:

• Improved exhaust flow for increased engine power and responsiveness.
• Enhanced sound characterized by an improved, yet road-legal acoustic experience.
• Optimized exhaust system weight and stainless steel construction supports vehicle longevity.
• Designed to fit the catalytic converter and Lambda sensors stock installation for emissions compliance.

These benefits contribute to an overall improved driving experience, both in style and performance, while ensuring compatibility and standards are met.

Krosfou exhaust systems are designed to be fully compatible with the OEM catalytic converters and Lambda sensors of the Audi A4 vehicle. They comply with European type approval standards such as E24-103R, ensuring they meet federal and local emissions laws, including California standards where applicable.

• Certified exhaust systems compatible with stock catalytic converters for seamless installation.
• Systems equipped with necessary oxygen sensor plugs and fittings.
• Note that some aftermarket downpipes requiring ECU reprogramming are not covered.

Always check local laws and regulations to ensure compliance before installing an exhaust system.

Krosfou exhaust systems come designed for bolt-on installation, directly fitting the original exhaust attachment points on Audi A4 vehicles. Depending on the model and generation, some installations may require slight modifications such as bumper cutting for RS4 or S-Line style rear end fittings.

• All required hardware including bolts, clamps, and gaskets are included for installation.
• Oxygen sensor plugs and caps provided where necessary.
• Detailed installation instructions are available to ensure correct fit and function.

Professional installation is recommended to ensure optimal performance and reliability.
