Upgrade your VQ-powered Nissan or Infiniti with the ISR Performance HGC Long Tube Headers, designed for VQ35DE and VQ35HR applications including the Nissan 350Z, Infiniti G35, and compatible 370Z VQ applications. These long tube headers are designed to improve exhaust gas flow by replacing the restrictive factory exhaust manifolds with longer, smoother-flowing primary tubes that help the engine breathe more efficiently. The HGC design is built for performance-focused VQ builds and is an excellent supporting modification for vehicles running other exhaust upgrades, including high-flow cats, test pipes, Y-pipes, and aftermarket cat-back systems. The improved exhaust flow can help support better throttle response, stronger mid-to-high RPM performance, and a more aggressive exhaust tone when paired with the rest of the system. Built with performance and durability in mind, ISR Performance long tube headers are a popular choice for VQ35 owners looking to maximize the potential of their naturally aspirated or modified setup while upgrading the overall exhaust system.
