JHM High Flow Cat for the B9-B9.5 Audi S4-S5 3.0T

Unleash the true potential of your turbocharged 3.0T engine with the JHM High Flow Cat. Specifically designed for the B9 and B9.5 Audi S4-S5, this high-flow catalyst is the definitive solution for enthusiasts looking to eliminate the primary bottleneck in the factory exhaust system.

 

By replacing the restrictive OEM unit with our optimized racing catalyst, you’ll experience immediate gains in horsepower and torque, significantly reduced turbo lag, and a more aggressive, sophisticated exhaust note that lets the V6 turbo breathe as it was meant to. Stage 2 software is recommended to prevent CEL.

Performance & Engineering

Designed and tested to withstand the rigors of high-performance driving, this unit features a Euro4 200-cell racing catalytic converter. Positioned in the factory location to maintain thermal efficiency, it allows for maximum flow without the heavy turbulence associated with the stock component.

Constructed from 304 Stainless Steel, each unit is TIG-welded for superior weld integrity. To protect your engine bay from heat soak, we’ve integrated an OE-style heat isolation barrier, ensuring that exhaust energy stays inside the piping and away from sensitive components.

Key Features:

  • Increased Power: Increases of up to 20+ HP and 30+ TQ.

  • Rapid Response: Quicker turbocharger spool (150-300 RPM sooner) and improved transient throttle response.

  • Premium Construction: Full 304 Stainless Steel with precision CNC-machined flanges for a leak-free seal.

  • Advanced Flow:  Euro4 200-Cell High-Flow Catalyst.

  • Thermal Management: Integrated heat shielding to minimize engine bay temperatures.

  • Direct Fit: A true bolt-on upgrade featuring integrated V-band and 3-bolt downpipe flanges.

     

What’s Included:

  • (1) JHM Stainless Steel Performance Downpipe with Integrated Euro4 Catalyst

  • (6) M8 Locknuts

  • (6) M8 Bolts

Note: This product is designed for North American models and is not compatible with vehicles equipped with a GPF (Gasoline Particulate Filter).
