The 034 Motorsport Stainless Steel Racing catalyst set for the Audi RS5 (B9 / B9.5) with the 2.9T engine is designed as a direct replacement for the limiting factory catalytic converters. This set provides performance improvements throughout the entire rev range: more power and torque, faster turbo spool, better throttle response, and a sportier exhaust sound, with less turbo lag and faster acceleration.
The set uses two large Euro 3 Racing catalytic converters in the original locations for a complete drop-in replacement without modifications to the factory components. Integrated V-band flanges on the turbo outlets, oxygen sensor connections after the catalytic converters, and 3-bolt downpipe flanges ensure a precise fit. The catalytic converters are manufactured from durable 304 stainless steel, TIG-welded and backpurged, with an OE-style thermal insulation barrier that minimizes heat transfer to the engine compartment.
