Porsche 911 991.1 GT3/GT3 RS Headers

Pure flow. Naturally aspirated precision.

The 2013–2016 Porsche 911 991.1 GT3 / GT3 RS Headers are engineered to maximize exhaust efficiency for Porsche’s high-revving naturally aspirated flat-six. By replacing the factory restrictive manifolds, these headers improve exhaust scavenging, allowing the engine to breathe more freely across the entire RPM range.

Designed specifically for the GT3 platform, this upgrade enhances throttle response, sharpens power delivery, and amplifies the signature high-pitched GT3 exhaust note — delivering a more raw and connected driving experience.

Constructed using precision TIG welding and mandrel-bent tubing, these headers ensure durability under extreme temperatures while maintaining optimal flow characteristics. Designed as a direct bolt-on solution, installation is seamless with no cutting required.

This isn’t about forced power.
This is about perfecting what’s already exceptional.

Key Features:
• Improved exhaust flow and scavenging
• Increased horsepower & throttle response
• Enhanced high-revving engine performance
• Sharper, more aggressive GT3 exhaust tone
• TIG welded construction
• Mandrel-bent piping for maximum efficiency
• Direct bolt-on installation
