Audi S4 / S5 B9 B9.5 3.0T Valved Catback Exhaust with Midpipe | Vortex

Unleash the True V6 Roar: The Ultimate Midpipe & Exhaust Upgrade

The Audi S4 and S5 (B9/B9.5) are powered by the phenomenal EA839 3.0T V6 engine, but the factory exhaust system—specifically the heavily restricted OEM midpipe and resonators—muffles its true potential. The Vortex Valvetronic Catback Exhaust System with High-Flow Midpipe is the definitive solution. By replacing the restrictive factory components from the downpipe back, this comprehensive system completely transforms your driving experience, delivering a dramatic increase in exhaust flow, sharper throttle response, and a deep, aggressive V6 growl that commands attention.

Uncompromising Material Options Built for pure performance and longevity, Vortex offers this complete system in two premium materials to suit your exact build requirements:

• Aerospace-Grade Titanium: The ultimate upgrade for the performance purist. Significantly reduces overall vehicle weight compared to the factory system while producing a distinctively sharp, exotic, and high-frequency resonance.

• Premium T304 Stainless Steel: The gold standard for extreme durability and daily driving. Offers exceptional corrosion resistance and a smooth, deep, and powerful rumble.

Key Performance Features

• Complete System with Midpipe: Unlike basic axle-back systems, our package includes a high-flow midpipe that eliminates factory resonators (resonator delete), maximizing turbo spool and unlocking the engine's true sound.

• Intelligent Valvetronic Control: Retain total command of your exhaust note. Keep the valves closed for a refined, stealthy cabin environment during daily commutes, or open them wide to let the 3.0T engine sing on the open road.

• Precision Fitment: 3D-scanned and engineered for a 100% direct bolt-on installation with no cutting or welding required. (Professional installation is highly recommended).

Vehicle Compatibility (Fitment) Perfectly engineered for the MQB Evo platform. Fits the following models:
