DE Short Tube Headers | 2003-2007 Nissan 350Z & 2003-2007 Infiniti G35 | Fits VQ35DE Non-RevUp & RevUp | 304 Stainless Steel | Gains +8-12 WHP | Direct Bolt-On

Wake up your 2003-2007 Nissan 350Z or 2003-2007 Infiniti G35 with these DE Short Tube Headers that ditch the restrictive OEM cast manifolds for free-flowing 304 stainless steel primaries, because the stock VQ35DE manifolds choke exhaust velocity and rob midrange torque while these are mandrel-bent with equal-length runners and CNC-machined flanges to improve scavenging, drop EGTs, and unlock a real +8-12 WHP and +7-10 WTQ on a stock tune with bigger gains when paired with a plenum spacer and catback, and they’re a direct bolt-on for all 2003-2006 350Z and G35 VQ35DE Non-RevUp as well as 2005-2007 RevUp models, clearing factory motor mounts, steering shaft, and AC lines while retaining the OEM heat shields and downstream cats or test pipes so you stay emissions compliant and inspection-friendly in most states, and the 1.5in primaries merge into a 2.25in collector with thick 3/8in flanges that resist warping and include high-temp graphite gaskets and new hardware so you get zero exhaust leaks, and the entire header is TIG-welded and back-purged for max strength then glass-bead blasted to resist corrosion and heat discoloration, and you keep full ground clearance with no low-hanging pipes, and the install uses your factory O2 sensor locations with no CEL or tuning required though a tune will maximize gains, and the sound gets deeper and more aggressive without rasp or drone when paired with stock cats, and every set is pressure-tested and checked for flange flatness so you get perfect fitment right out of the box, making these the easiest bolt-on power mod for your DE 350Z or G35 that adds real dyno-proven gains, better throttle response, and that proper VQ tone without the fitment headaches of cheap long tubes.
