Porsche 911 GT3 / GT3 RS (991) 4.0L Racing Valvetronic Performance Exhaust (2014-2019) - Vortex

Porsche 911 GT3 & GT3 RS (991) 4.0L "Racing Series" Valvetronic Exhaust - Vortex®

From the Track to the Street: The Unfiltered 9000 RPM Experience

The 4.0L Flat-Six in the 991 GT3 and GT3 RS is a masterpiece of motorsport engineering. However, the factory exhaust system—designed for road compliance—often acts as a silencer, muting the raw mechanical brilliance of this 9000 RPM legend.

Vortex® has engineered the "Racing Series" exhaust specifically for the 4.0L platform. This isn't just an exhaust; it’s a high-performance instrument designed to eliminate backpressure, shed significant weight, and deliver a visceral, high-definition soundtrack that mirrors the Porsche RSR and Cup cars.

### Vehicle Compatibility & Fitment

Precision-designed for a 100% bolt-on fitment for all 4.0L-equipped 991 chassis:

### Technical Highlights

• Racing Valvetronic Control: Command your vehicle's voice via remote control or factory-integrated console buttons.

  • Refined Stealth: Valves closed for a sophisticated, drone-free experience during street cruising or professional arrivals.

  • Racing Unleashed: Valves wide open to unleash the full, unfiltered 4.0L symphony, featuring razor-sharp metallic notes and aggressive downshift blips that command the track.

• Premium Material Engineering:

  • T304 Stainless Steel: For a deep, muscular resonance and lifelong durability against the extreme thermal stress of high-revving track sessions.

  • Grade 5 Aerospace Titanium: The ultimate upgrade for the GT3 RS. Significantly reduces weight behind the rear axle for sharper handling agility and provides that exotic, high-frequency metallic bark only possible with titanium.

• Artisanal Craftsmanship: Every Vortex® system features our signature hand-laid TIG fish-scale welding. This ensures maximum structural integrity under extreme vibrations while looking like a work of art under your Porsche.

• Racing High-Flow Geometry: Developed using 3D laser scans of the 991 chassis to ensure perfect clearance and improved exhaust gas velocity, resulting in sharper throttle response and increased mid-range torque.
