Porsche 911 991.1 GT3 & GT3 RS Full Valved Exhaust with 200-Cell Catted Headers

Transform Your Porsche 911 991.1 GT3 or GT3 RS with 200-Cell Headers and a Titanium Valved Exhaust

Designed for the Porsche 911 991.1 GT3 3.8L and GT3 RS 4.0L, this full performance exhaust system combines high-flow 200-cell catted exhaust headers with a lightweight valved titanium exhaust system for a comprehensive upgrade from the engine outlets through the rear exhaust section.

The headers are manufactured from high-quality 304 stainless steel and incorporate 200-cell high-flow catalytic converters, while the rear exhaust system uses titanium alloy construction with high-temperature TIG welding. This combination helps reduce exhaust restriction, supports improved gas flow and delivers a sharper, more aggressive naturally aspirated flat-six exhaust character while retaining a catted header configuration.

Professional installation is recommended to ensure correct alignment, sealing, valve operation and integration with the vehicle's existing exhaust components.
