Audi RS4 / RS5 B9 2.9T SS304 Exhaust System
Unleash the true power of your Audi RS4 / RS5 B9 2.9T with our SS304 exhaust system

If your B9 model’s 2.9L twin-turbocharged engine is held back by the restrictive stock exhaust system, these precision-engineered SS304 exhaust pipes are the key to unlocking power, sound, and responsiveness.

Built for Performance and Durability
Crafted from premium 304 stainless steel, they are designed to withstand high temperatures and daily use while resisting corrosion, ensuring a lifespan of many years. Smooth, center-bend construction eliminates flow restrictions, reduces backpressure, and allows your turbocharger to breathe freely.

Tangible Performance Gains
Increased horsepower and torque across the entire RPM range
Reduced turbo lag for instant throttle response
Lower exhaust gas temperatures (EGT) for safer, more stable performance

Deeper, More Aggressive Sound
Replace the restrictive stock exhaust with a straight-through or high-flow configuration, unlocking a deep, raw sound for your RS. No screeching—just a pure, refined exhaust note that turns heads.

Direct bolt-on installation
Precision CNC-bent tubing and factory-style mounting interfaces mean no cutting, no modifications, and no hassle. Plug-and-play installation, designed specifically for the Audi RS4 / RS5 B9 2.9T models. Also features OEM sensor connectors for easy integration.

Why Upgrade?
Your RS4/RS5 was built for performance—don’t let the factory exhaust system hold it back from reaching its full potential.
These exhaust pipes are the ultimate step for any enthusiast eager to unlock the true performance limits of the B9 models.
