Exhaust Manifolds FMIC.Pro for Porsche 911 991.1 Carrera S 3.4 3.8 2012-2016

FMIC.Pro performance exhaust manifolds are an advanced upgrade to the factory exhaust system. The extended runner design significantly improves exhaust gas flow, resulting in measurable gains in horsepower, torque, and faster engine response.

The manifolds are manufactured from high-grade 304 stainless steel, resistant to extreme temperatures and corrosion. Precision CNC-cut 10 mm thick flanges and TIG welds ensure perfect fitment, leak-free operation, and long-term durability – suitable for both street vehicles and performance builds.

Optimized pipe diameter and smooth bends eliminate factory exhaust restrictions, delivering a deeper, aggressive exhaust tone while maintaining smooth engine operation.

The integrated heat shield mounted on the exhaust manifold reduces heat radiation into the engine bay. It protects surrounding components (wiring harnesses, hoses, plastic covers) from excessive temperatures.
