JHM High-Flow Stainless Steel Racing Catalyst Set | B9/B9.5 Audi RS5

Unlock the true potential of your 2.9T biturbo engine with the JHM Stainless Steel High-Flow Catalysts. Engineered as a high-performance alternative to the restrictive OEM units, this set is the definitive solution for B9/B9.5 RS5 owners seeking to eliminate exhaust backpressure and maximize power output.

By replacing the factory bottlenecks, JHM delivers a noticeable surge in horsepower and torque across the entire RPM range and a more aggressive, raw exhaust note.

Built for enthusiasts who demand longevity and performance, these catalysts are crafted from 304 stainless steel. To ensure structural integrity under extreme heat, every unit is TIG Welded. We’ve also integrated an OE-style thermal heat shielding to keep engine bay temperatures low, protecting sensitive components from heat soak.

This is a comprehensive, bolt-on kit designed for a seamless installation. 


Key Features

  •  Increased output and broader torque curves across the powerband.

  •  Improved turbocharger transient response, hitting peak boost sooner than stock.

  • Pronounced exhaust tone and audible turbocharger spool.

  • Dual 200 CPI Euro4 racing catalytic converters positioned in the factory location.

  • Integrated heat isolation shielding to minimize engine bay soak.

  • CNC-machined v-band and 3-bolt flanges ensure a leak-free seal.
