Unleash the full potential of your Audi S3 with our Stage 2 Performance Package — a complete, performance-driven system engineered to deliver serious power, enhanced cooling, and a commanding exhaust note to match the S3’s quattro all-wheel-drive performance.

Designed for drivers who demand more than just a tune, this Stage 2 package provides the airflow, thermal control, and exhaust efficiency required to push the EA888 platform well beyond factory limits — while maintaining reliability, refinement, and everyday usability.

Built around premium materials and proven hardware, this package transforms the Audi S3 into a sharper, faster, and more aggressive performance machine.

What’s Included

Full Blue Titanium Valved Exhaust

Crafted from lightweight titanium with a stunning burnt blue finish, this valved cat-back exhaust delivers significant weight reduction and improved exhaust flow. The integrated valve system allows you to switch seamlessly between a refined, quiet cruising mode and a fully open, aggressive race-inspired tone at the push of a button — perfect for both daily driving and spirited runs.

Upgraded Front-Mount Intercooler

(Core Size: 620mm x 440mm x 65mm)

Featuring a massive high-efficiency bar-and-plate core, this intercooler dramatically improves charge-air cooling over the factory unit. By reducing intake air temperatures and preventing heat soak, it ensures consistent power delivery under hard driving, higher boost levels, and repeated pulls — essential for tuned Audi S3 builds.

Heat-Shielded Catless Downpipe (3.0”)

Engineered for maximum exhaust flow, this 3.0” catless downpipe removes factory restrictions to allow the turbocharger to spool faster and operate more efficiently. Integrated heat shielding helps reduce engine bay temperatures, while precision TIG-welded 304 stainless steel construction ensures durability under extreme heat and performance conditions.

Titanium Charge Pipes

While not required for Stage 2 power levels, upgraded titanium charge pipes are strongly recommended for customers seeking maximum reliability and performance consistency. The factory plastic charge pipes can become a weak point under increased boost pressure, particularly on aggressively tuned vehicles.

Manufactured from lightweight aerospace-grade titanium, these charge pipes provide superior strength, improved airflow efficiency, and greater resistance to heat and pressure. They also enhance engine bay aesthetics with their signature burnt titanium finish while ensuring long-term durability for both Stage 2 and future big turbo applications.

This upgrade is especially beneficial for customers planning to progress to Stage 3 in the future, as it provides a stronger and more reliable boost pathway.

Performance Benefits (When Tuned)

With the appropriate Stage 2 calibration, this package has the potential to deliver:

• +50–80 HP and +90–120 Nm of torque (depending on tune and supporting modifications)
• Faster turbo spool and sharper throttle response
• More consistent power delivery thanks to improved cooling efficiency
• Reduced exhaust backpressure and enhanced turbo efficiency
• Adjustable exhaust volume — from subtle OEM+ to aggressive performance sound
• Improved boost reliability and durability when paired with optional titanium charge pipes

Important Tuning Notice

Proven Performance Parts does not offer ECU tuning, flashing, or calibration services, and this package does not include a tune.

A custom Stage 2 tune is required to achieve performance gains, and customers must arrange tuning independently through a professional tuner of their choice.

Final performance results will vary depending on tune quality, fuel used, vehicle condition, and supporting modifications. Poor or unsafe tuning may reduce performance, reliability, and overall drivability.

Why Choose Our Stage 2 Package?

Each component in this package delivers strong gains on its own — but together, they form a balanced, high-performance system designed specifically for Stage 2 power levels.

From the lightweight titanium exhaust to the oversized intercooler and free-flowing downpipe, every part has been selected to work in harmony for maximum performance, durability, and driving enjoyment.

With the addition of optional titanium charge pipes, customers can further strengthen their setup and prepare their vehicle for future power upgrades.

This is Stage 2 done properly — engineered, tested, and curated by enthusiasts who understand what it takes to unlock real performance from the Audi S3.
