Description
The 034 Motorsport Stainless Steel Racing Catalyst for Audi SQ5 B9 and B9.5 platforms is a high-performance, factory-location upgrade engineered to significantly improve exhaust flow, turbocharger efficiency, and overall engine performance. Designed as a direct bolt-in replacement for the OEM catalytic converter, this system delivers increased power while maintaining precision fitment and durability.
Optimized for maximum flow and performance, this racing catalyst features a massive 148mm diameter Euro4 200-cell high-flow catalytic converter positioned in the factory location. The design includes an integrated V-band flange at the turbine outlet, integrated oxygen sensor bung positioned after the catalyst, and integrated 3-bolt downpipe flanges for seamless installation.
Manufactured from premium 304 stainless steel, the system is TIG-welded and backpurged to ensure long-term durability, corrosion resistance, and structural integrity. An OE-style heat isolation barrier is also integrated to reduce exhaust heat transfer into the engine bay, improving thermal management under demanding conditions.
This system was fully developed in-house by 034Motorsport using advanced 3D scanning, CAD engineering, and rapid prototyping. It was then extensively tested on both B9 and B9.5 Audi SQ5 vehicles under real-world and track conditions to ensure reliability and performance gains.
