DC Sports Stainless Steel Headers 2003-2007 Nissan 350Z Infiniti G35 VQ35DE
Transform the performance and sound of your VQ35DE engine with DC Sports Stainless steel Exhaust Headers engineered specifically for the 2003-2006 Nissan 350Z and 2003-2007 Infiniti G35 Coupe and Sedan, designed to replace the restrictive OEM cast iron manifolds that choke exhaust flow and limit power potential by using mandrel-bent T304 stainless steel construction with precision-welded CNC machined flanges for a leak-free seal and optimized equal-length primary tubes that merge into a high-velocity collector to dramatically improve exhaust scavenging, increase throttle response, and deliver dyno-proven gains of 12-18+ wheel horsepower and stronger midrange torque throughout the entire powerband while producing a deeper, more aggressive V6 exhaust note under acceleration, and each set is finished in a high-temperature ceramic thermal coating rated for over 1300°F that significantly reduces under-hood temperatures to protect surrounding wiring and components while maintaining higher exhaust gas velocity for improved efficiency and performance, and this direct bolt-on design retains compatibility with your factory catalytic converters or aftermarket test pipes and catback systems with all necessary hardware and multi-layer steel gaskets included for a complete installation, making these headers one of the most effective bolt-on modifications for naturally aspirated or boosted DE engines by freeing up lost horsepower and improving overall engine breathing, and the stainless steel also provides superior corrosion resistance against heat cycling and road elements to ensure long-term durability and appearance for street, track, or daily driven builds, with fitment confirmed for all 2003-2006 350Z and 2003-2007 G35 models and professional installation plus ECU tuning recommended to maximize gains and eliminate check engine lights when used with catless setups, giving DE-powered Z and G owners a proven, quality upgrade backed by DC Sports’ decades of experience in import performance exhaust design.
