Product Description

This high-performance valvetronic exhaust system is customized for Infiniti FX37 3.7L V6 naturally aspirated models with VVEL variable valve engine. The factory stock exhaust features restrictive piping and muffler design, causing high exhaust backpressure, limiting engine ventilation efficiency, resulting in slow throttle response, insufficient high-speed power and dull exhaust sound, failing to release the 3.7L V6 engine’s inherent performance.

Made of premium T304 stainless steel with integrated mandrel bending and precise TIG welding, this exhaust boasts high temperature resistance, anti-corrosion and long-lasting durability. The optimized high-flow pipeline effectively reduces exhaust resistance, accelerates exhaust gas discharge, improves engine breathing and significantly enhances throttle sensitivity and high-rev power output. Equipped with wireless remote control valve, it switches freely between quiet daily cruising and aggressive sport mode, eliminating annoying resonance drone. All OEM mounting points and sensor ports are perfectly reserved for 100% bolt-on installation without cutting or drilling. Ideal for street modification, supporting global wholesale, OEM and ODM customization services.
