DC Sport Race Headers | 2009-2020 Nissan 370Z & 2008-2013 Infiniti G37/Q60 | Fits VQ37VHR | 4-2-1 Design | +18-25 WHP Gains | CARB Legal Pending | Full 304SS
Unleash the VQ37VHR in your 2009-2020 Nissan 370Z or 2008-2013 Infiniti G37/Q60 Coupe and Sedan with DC Sport Race Headers, a proven 4-2-1 equal-length design that replaces the restrictive OEM manifolds with high-flow 304 stainless steel to unlock real power and sound, because stock VHR manifolds choke exhaust flow and kill midrange while these mandrel-bent primaries merge in a tuned 4-2-1 layout for massive torque gains down low and strong top-end pull, delivering dyno-proven +18-25 WHP and +15-20 WTQ on 93 octane with supporting mods, and they’re a direct bolt-on for all 2009-2020 370Z Base, Touring, Sport, Nismo, and 2008-2013 G37/Q60 Coupe, Sedan, Convertible, AWD, and IPL VQ37VHR models, clearing motor mounts, steering shaft, and AC lines with no cutting or denting while using heavy-duty 3/8in CNC-machined flanges and multi-layer steel gaskets to eliminate warping and leaks, and the headers retain OEM O2 sensor bungs so they work with stock cats, high-flow cats, or test pipes and keep full ground clearance for lowered cars, and every set is TIG-welded, back-purged, and polished for corrosion resistance and long-term durability, and the 4-2-1 design gives you deeper tone at idle with a clean, aggressive rasp-free scream up top that pairs perfectly with catback exhausts, and install uses your factory hardware locations with no CEL on stock ECU though a tune is recommended to maximize gains, and DC Sport pressure-tests and inspects every header for flange flatness and weld quality so you get true bolt-on fitment, making these the best value VHR header if you want proven DC Sport engineering, daily-drivable power, and that proper VQ sound without the fitment headaches of no-name brands.
Key Features:
- Fits 2009-2020 370Z & 2008-2013 G37/Q60: Direct bolt-on for all VQ37VHR models. Base, Touring, Sport, Nismo, Coupe, Sedan, Convertible, AWD, and IPL supported.
- Dyno-Proven +18-25 WHP Gains: 4-2-1 equal-length design boosts midrange torque and top-end power. Adds +15-20 WTQ with tune and supporting mods.
- True 4-2-1 Tri-Y Layout: Tuned primary and secondary lengths maximize scavenging. More usable torque down low vs 4-1 designs.
- Full T304 Stainless Steel: Mandrel-bent 304SS primaries and collectors. TIG-welded and back-purged for strength and corrosion resistance.
- Thick 3/8in CNC Flanges: Precision-machined flanges stay flat under heat cycles. Eliminates warping and exhaust leaks common on cheap headers.
- Multi-Layer Steel Gaskets Included: High-temp MLS gaskets seal better than graphite. Included with new hardware for leak-free install.
- Retains OEM O2 Sensor Locations: Works with stock cats, high-flow cats, or test pipes. No CEL on stock ECU, but tune recommended.
- Clears Motor Mounts & AC Lines: Engineered around VHR engine bay. No denting, cutting, or relocating needed for install.
- Maintains Factory Ground Clearance: Tucked design with no low-hanging pipes. Safe for lowered cars and daily driving.
- Deep Tone with Clean Top-End: Aggressive idle and midrange growl with rasp-free scream up top. Pairs well with any catback.
- Polished Finish Resists Bluing: Electro-polished surface slows heat discoloration and corrosion. Stays clean longer than raw stainless.
- Pressure-Tested for Leaks: Every set checked for weld integrity and flange flatness. True bolt-on fitment out of the box.
- Works with Stock or Aftermarket Exhaust: Bolts to OEM cats and any catback. Build your setup in stages without fitment issues.
- Street-Friendly Power Band: Makes real gains from 3k-7.5k RPM. Not just peak numbers, improves daily drivability and track response.
- DC Sport Backed Quality: Decades of header engineering and US-based support. Proven on VHR platforms vs untested no-name brands.
