Exhaust Manifold Headers FMIC.Pro for Nissan 350Z 370Z Infiniti G35 VQ35 VQ37 2003-2020

FMIC.Pro performance exhaust headers are an advanced exhaust system upgrade designed specifically for Nissan / Infiniti VQ-series engines. The long-tube design significantly improves exhaust gas flow, resulting in measurable gains in horsepower, torque, and faster engine response.

The headers are manufactured from high-grade 304 stainless steel, offering excellent resistance to extreme temperatures and corrosion. Precision CNC-cut 10 mm thick flanges combined with TIG welding ensure perfect fitment, leak-free operation, and long-term durability — suitable for both street cars and high-performance tuning projects.
Optimized pipe diameter and smooth mandrel bends eliminate factory exhaust restrictions, delivering a deeper, aggressive, and sporty exhaust tone without sacrificing smooth engine operation.
