FLASHARK's downpipes are designed to seamlessly replace your restrictive stock downpipes, positioned just after the catalytic converters. These upgraded downpipes significantly enhance horsepower and torque on turbocharged Audi S4 B5, A6 C5, and Allroad C5 models with the 2.7L BiTurbo V6 engine. By allowing exhaust gases to flow more freely from the turbo, they reduce turbo lag and increase power. Made from high-quality stainless steel, these downpipes improve exhaust airflow, providing a smoother driving experience and optimizing your Audi’s overall performance.

What does a Downpipe do?

The downpipe exhaust on your Audi S4 B5, A6 C5, or Allroad C5 with the 2.7L BiTurbo V6 engine directs exhaust gases from the turbocharger to the rest of the exhaust system. An aftermarket downpipe, such as the FLASHARK Catless Downpipe, is typically larger in diameter, either removing the catalytic converter or replacing it with a high-flow unit. This upgrade significantly improves exhaust flow, allowing gases to exit the turbo more efficiently. By replacing the restrictive factory downpipe, you reduce turbo lag, increase horsepower and torque, and enable higher boost levels. This removal of factory restrictions maximizes your Audi’s performance and enhances the driving experience.
