High-Flow Catless Downpipe with Heat Shield for Audi SQ5 B9 3.0 TFSI Turbo V6
Designed for the Audi SQ5 B9 powered by the EA839 3.0 TFSI turbocharged V6, this high-flow catless downpipe replaces the restrictive factory catalytic converter section with a significantly freer-flowing exhaust path directly after the turbocharger.
Manufactured from high-quality stainless steel, the downpipe is engineered to withstand extreme exhaust temperatures while providing excellent strength, corrosion resistance and long-term durability.
An integrated metal heat shield helps reduce radiant heat around the downpipe and surrounding engine-bay components, providing additional thermal protection in the high-temperature turbocharger area.
The catless configuration removes the restrictive factory catalytic converter, significantly reducing post-turbo exhaust restriction and allowing exhaust gases to flow more efficiently. This results in increased turbocharger sound together with a deeper, louder and more aggressive 3.0 TFSI V6 exhaust note.
The freer-flowing design is particularly suited to tuned and performance-oriented EA839 3.0 TFSI builds where reduced exhaust restriction and improved turbocharger response are a priority.
Vehicle-specific routing, flange geometry and mounting points are designed around the factory Audi SQ5 B9 exhaust system. Original sensors and applicable OEM components should be transferred during installation where required. Professional installation is strongly recommended.
