Audi RS5 High Flow Downpipes

Audi RS5 High Flow Downpipes

Engineered for drivers who don't just want performance—they demand presence. This set of high flow downpipes for the Audi RS5 removes the restrictive factory catalytic converters, unlocking the twin-turbo V6's full potential with sharper spool, stronger mid-range, and a deeper, more aggressive exhaust note.

Fitment

• Audi RS5 (B9/B9.5)
• Direct bolt-on, no cutting or modification required
• Compatible with factory or aftermarket tuning
• Pairs seamlessly with factory or aftermarket catback systems

Sound Character

This system is built to amplify what makes the RS5 special—its twin-turbo V6 character—while unlocking real performance gains.

• Sharper, more mechanical tone at idle and cruise compared to the restrictive factory setup
• Increased turbo spool presence and boost-building character under acceleration
• A more aggressive, race-inspired snarl through the mid-range and top end
• Pronounced turbo overrun crackle and pop on lift-off

Materials & Engineering

• Constructed from premium T304 stainless steel for superior corrosion resistance and longevity
• Precision TIG-welded for structural integrity and clean aesthetics
• Mandrel-bent tubing ensures optimal exhaust flow and reduced backpressure
• High-flow cats (where equipped) maintain proper O2 sensor function and minimize check engine light concerns
• Designed to reduce weight vs. factory downpipes while improving turbo response

Performance Benefits

• Significantly increased exhaust flow for improved horsepower and torque
• Reduced backpressure for faster turbo spool and stronger mid-range pull
• Noticeable weight savings over OEM downpipe components
• Enhanced driving engagement through sound and responsiveness
• Ideal foundation for tuned builds looking to maximize the RS5 platform

What's in the Box

• Full stainless steel high flow downpipe set
• All required clamps, hardware, and gaskets
• Installation guide

Why This System

The RS5 already delivers serious performance—but from the factory, restrictive catalytic converters hold back the twin-turbo V6's true potential. This system removes those limitations and unlocks the raw, emotional experience the platform was built for.

If you're the kind of owner who values precision engineering, track-ready performance, and a sound that turns every drive into an event—this is the upgrade that completes the car.
