Porsche 911 991.1 Carrera 4S 3.8L Performance Exhaust Headers with Heat Shield (2013–2015)

Improve Porsche 911 991.1 Carrera 4S 3.8L Exhaust Flow and Response with Performance Exhaust Headers

Designed for the Porsche 911 991.1 Carrera 4S 3.8L, these high-flow exhaust manifolds provide a performance-focused replacement for the restrictive factory exhaust headers. The optimized design improves exhaust gas flow and helps reduce backpressure for sharper engine response and a more aggressive exhaust character.

Constructed from high-quality 304 stainless steel, the manifolds feature integrated heat shields to help control exhaust temperatures and protect surrounding components. Durable welded construction and a direct-fit layout make them a strong upgrade for both standard and modified Porsche 991.1 Carrera 4S applications.

Professional installation is recommended for correct fitment, sealing and alignment.
