Unlock the real potential of your 2014-2024 Infiniti Q50, 2008-2013 G37/Q60, or 2009-2020 Nissan 370Z with these VQ37VHR Short Tube Headers that replace the restrictive OEM cast manifolds with mandrel-bent 304 stainless steel primaries designed to maximize scavenging and exhaust velocity on the 3.7L VHR, because stock manifolds choke flow and flatten midrange torque while these equal-length runners with tuned 1.625in primaries merging into 2.5in collectors deliver dyno-proven +12-20 WHP and +10-16 WTQ gains with sharper throttle response and a deeper, aggressive VQ tone that stays clean without rasp or drone, and they’re a direct bolt-on for all Q50 RWD/AWD including 3.7, 3.0t, Red Sport, and Luxe trims, plus G37/Q60 Coupe, Sedan, Convertible, IPL, and 370Z Base, Touring, Sport, Nismo with manual or automatic transmissions, clearing factory motor mounts, steering shaft, AC lines, and heat shields with no cutting, denting, or relocating required, and the headers retain OEM O2 sensor locations and bolt to stock cats, high-flow cats, or test pipes so you stay emissions-friendly and inspection-safe with no CEL on a stock ECU though a tune will maximize gains, and they use thick 3/8in CNC-machined flanges and high-temp multi-layer steel gaskets to eliminate warping and leaks, while every set is TIG-welded, back-purged, and polished to resist corrosion and blue discoloration from heat cycles, and the shorty design maintains full factory ground clearance so you get gains without scraping on lowered cars, and install uses factory hardware locations with no ECU work needed, and every header is pressure-tested and checked for flange flatness so you get perfect fitment out of the box, making these the smartest bolt-on power mod for your VQ37VHR Q50, G37, Q60, or 370Z if you want proven stainless construction, daily-drivable torque, and that signature VQ sound without the fitment headaches and reliability issues of cheap long tubes.
